New Tiguan Lane Assist and Side Assist Retrofit

Tiguan New 2018 Retrofitting Lane Assist and Side Assist 


My old customer who had his 2008 CC retrofitted with Lane Assist and Side Assist years back, came knocking on my door. He got himself a brand new Rline 2.0 AWD Tiguan 2018. After 6 months of pure form original ownership, he got bored and decide to get back to his roots. 

His R Line Tiguan is already very well spec at factory. It has Adaptive Cruise Control which is only available on this model not even found on the top of the line Arteon 2.0 AWD ! Surprising but it is true. It has also Head Up Display but I find it of little use since the Digital Cluster aka Advanced Info Display is right in front of him displaying all the details required in various form. Why do you need a HUD ? Nice to have I would guess but IMHO, it is not necessary. 

As usual, retrofitting the Lane Assist requires his brand new flawless windscreen to be replaced. This is inevitable.

Original rear mirror is reused. The new housing hides the camera.
 ( the wires are for the event camera - only place for the wires )

Next, we installed the Side Assist aka Rear Assist aka Rear Traffic Assist aka Lane Change Assist aka Rear Traffic Alert. So many names but only one function. 

Removal of the bumper is necessary to install the two radar sensors and run the wiring harness into the cabin.

Heater Seat Retrofitting on Golf 7 : Is it viable ?

Retrofitting Heater Seats on Volkswagen Golf 7.3

Is the heater seat useful in tropical hot Singapore ? I guess it is not in most cases. However for those with back ache or injuries or old tired backbones, the comfort of heat applied to the back whilst driving is a comfortable thing that only some can appreciate. 

Ladies during their "days" also love the heater seat soothing comfort for those cranky pain. My lady passengers swear by them. 

Many of the Volkswagen Trendline, Comfortline and even some Highline models do not have the heater seats fitted at factory anymore. These were common options on earlier models in the Volkswagen range but due to cost ( keeping OMV low ), VCS have deleted this option for most of the baseline models.  

Have received many inquiries about the retrofit of the seat heaters. I had made a study on the possibility of the work. Here are my findings : 

1. The heater element is not supplied as a separate part. This mean that you cannot buy the heater coil or element and replace it when it is faulty aka shorted or burned. 

2. The heater element is supplied as part of the cushion aka it is built inside the foam for the seat and back rest.  This mean that if your original heater is damaged, you need to replace the respective foam padding....i.e. seat foam or back rest foam. 

3. The heating function is performed by the Central Electric Module which is a common part in all VW cars. However, there are many variants. If the car is not originally fitted with the seat heating, the CEM supplied would be a low variant which does not have the necessary circuit to support the heating element function. 

4. The control of the heater seat is done via the Climatronic Control module. The seat icon can be seen on both side of the controller.  A new Climatronic module is needed if retrofit is to be done. 

5. Programming of the new Climatronic module is needed to enable the heater function. No additional wiring is required between the modules. 

6. Power to the CEM for the heaters is supplied from Fuse # 27 on the glove box fuse box. The fuse is supplied with 12 volt power but no wiring to the CEM. A good gauge wire need to be added from the fuse box to the CEM connector. 

In conclusion, it would be a costly exercise to retrofit the heater seat considering the above requirements. No a viable task unless it a die-die requirement for the heater seat to be available. 

My 2015 Golf Mk VII did not come with the heater seats much to my disappointment when I first purchased it. Seems that even on the EQP version, the heater have been deleted. 

I have replaced my seats with the GTE seats from Germany. They came with heaters. I had also replaced the CEM on my Golf when I upgraded to the Golf R Headlights . So, all I need was the wiring to connect the seats to the CEM and a new Climatronic controller.

Optical Parking System OPS on New Touran : V4

New Touran Retrofitting OPS V4 Optical Parking System ; Self Parking

The new Touran High Line does not come with VW Self Parking OPS aka Optical Parking System V4. This latest version is found on all the High Line models such as Tiguan Rline, Passat Exclusive, etc. Strangely, this option is not on the Passat Highline or RLine but only on the Exclusive. 

After the installation, the customer is able to do the self parking of the Touran. A feature that the wife loves 101% . 

This customer indented his Touran special from VW and have it equipped with the Lane Change Assist aka Side Assist.  This option automatically compliment the OPS V4 with Blind Spot Assist. 

The Lane Change/Side Assist radar behind the rear bumper

Arrangement was done by his sales person not to install the ugly two sensor reversing warning alert fitted at VW PDI center in Tuas. That save the bumper from having extra two holes which are the wrong size. The 12 sensors of the V4 OPS was fitted on the front and rear bumpers in their original positions. 

The new control switch panel which includes the electric tailgate button (next project for the customer)

New function on HU : Parking & Maneuvering

Control of volume and pitch for the front & rear buzzer

New feature Maneuver Braking and Rear Traffic Alert aka Blind Spot Monitoring.
The new features for the V4 OPS includes the Maneuver Braking which automatically applies the brake for the vehicle should it encounter an object during low speed moving of the vehicle. This works for front and rear sensors. 


Point to note. This feature would not work during normal driving at speed or at car park speed. It is only meant for parking manuever at low speed. 


The Blind Sport or Rear Traffic Alert is explained here on my blog 


Here is a video to give better visual and audio experience

Dynaudio Excite Retrofit on Golf 7

Retrofitting MIB2 Dynaudio Excite MIB2 Discovery Pro : Golf 7 VII 



The original 8 speaker sound quality of the typical Golf 7 is pretty decent when it is equipped with the Discovery Pro head unit. The built in amp produces reasonably good quality sound thru it's 4 channel system aka 8 speakers system. 

To enhance the sound quality, Volkswagen have the specially tuned Dynaudio sound system for their cars.  The highlights of the Dynaudio system extracted from the Dynaudio website is as follow :


Features & Highlights

  • Dual voice coil subwoofer offers optimized in-car bass performance
  • Authentic replication of the Dynaudio sound experience from the home or studio into your car
  • Solid bass performance no matter which seat one is sitting in
  • Mid/bass and subwoofer integration offers a cohesive and balanced bass experience in the car
  • MOST150 digital optical connection minimizes noise on the sound signal, maintaining a clear signal from the radio or media centre to the amplifier to allow for a pure listening experience
  • Shark DSP enables impeccable timing, placing the music in the perfect position in front of the listener while maintaining all spectra of the sound
  • Automatic sound adjustment to compensate for noise sources relative to the vehicle’s speed while maintaining the sound volume; the Dynaudio sound system functions in such a manner that the volume is automatically adjusted according to the cabin conditions to remain at the same level
  • Dynaudio fine tuning optimizes the sound tuning for each specific car model, as the different Golf variants are not completely identical; Dynaudio fine sound tuning ensures an uncompromised sound tailored to each specific vehicle
  • High performance 6.5 inch diameter MSP mid/bass drivers
  • Focus features: All, driver, co-driver or rear.
Here is the link to their write up 


Retrofitting the MIB2 Excite Dynaudio10 speakers on my special edition Golf 7.3 is a tedious job. It can only be fitted to the Discover Media or Discovery Pro Head Units because of the fibre optics requirement.  The communication between the DP HU and amplifier is via the fibre optic cables. There are no hard wires between the amp and the car's gateway unlike the earlier Dynaudio systems. 

Necessary removal for running of fibre optic cable
A specially fabricated harness connects up all the speakers to the amplifier and link to the Discover Pro via a pair of fibre optics cable.  My Golf have the Advanced Info Display cluster which has the fibre optics cable already as such, we needed to modify the cable to a 3 way split configuration combing the original AID and the Dynaudio cable set. 


Specially modified 3 way split Fibre Optic harness for AID/Dynaudio/DiscoveryPro


The Excite system comprises of a 400 watts digital amplifier/sound processor, 4 base/mid door speakers, 4 treble tweeters and a 2-speaker woofer box which fits over the spare wheel cavity. ( The Passat have a 12 speakers 650 watts system ! )

The amplifier is located under the left passenger seat

Conclusion :

The installation and online coding was a tedious process but the effort paid off with the tremendous improvement in sound quality. Music pieces that I have never sounded better and clearer before. 

A definite worthy upgrade to the sound system which is worth the work and money spent. Highly recommended !

Passat B8 Active Info Display Upgrade : Highline

Upgrading the Highline Passat B8 : Digital Instrument Cluster / Active Info Display

The customer purchased the Highline B8 recently. The analogue cluster did not go down well with him after he has seen them on the 2.0 Rline and Exclusive models.  We have the solution for him ! 

Ordered all the necessary parts from Germany and in 2 weeks, all the parts were here.  Online coding of the cluster is necessary to make everything work properly. 

Removed the original analogue cluster and installed the AID cluster

First time switching on, the cluster is full of errors ! The car would not start naturally since the cluster have not been paired. 

After all is done, input the original mileage in the AID. 

Fitting the connection between the HU and AID is required
Fit the new AID Trim Panel

AID would display the driver's view perspective of map view
