I'm sure some of you remember I posted about this issue a while back. However, we're still having issues.
So my buddy has a 2008 Seat Altea 2.0 FSI.
How the issue started (Chain of events )
He fitted some aftermarket HiD lights (Fogs and Mains ) - which I got for him from the same supplier of my lights.
The lights worked fine - except every now and then, the one light would flicker for a few seconds, then return to normal.
Fast forward a few months - he was on his way to Durban, when it started raining very heavily, so, he turned wipers onto full speed and also had front fogs on due to low viability. Once the rain stopped, he tried to turn the wipers off - however even taking the key out of the ignition, the wipers were still going full speed.
So, he disconnected the battery and obviously this stopped the wipers. He then reconnected the battery and wipers have ceased to work ever since then. Along with the auto lights feature which doesn't work.
After some extensive research - he concluded that it must have been the control unit under the dash that has blown. This unit controls ALL electronics in the car - without it plugged in, nothing works.
So it was safe to assume this is where we should look first.
So, after some months (Trying to find a this part was a mission), we decided to buy a second hand unit from ACE Auto in Springs (They had a smash red Leon there) the second hand part has the same part number - so we assume its the same thing.
On Saturday, we decided to fit it - although we thought it may need to be coded (We did speak to G60 golf, (Morne)) about this and he told us to just fit it and see how it goes.
After fitting it, we have same issues - unit has not helped. The car started and all other electronics worked, so I doubt it still a coding issue?
We then checked the following on the car:
- 1. Control Unit (as mentioned above)
2. ALL fuses / relays in the car - no problems there
3. All wires to and from the wiper motors - the outer coating on some wires were damaged - but otherwise fine
4. Measured power at the wiper motor plugs to see if power was even going there - it was.
However, we have no way of testing the motors, without buying new ones and possibly wasting more money on them.
The car comes with two motors for wipers and it's my understanding that when one blows, the other one doesn't work either?
When turning the wipers on / all - there is no noise or even slight movement from both motors / control arms.
The car is due for a visit to Morne this week - I know he is very busy, so hence me asking here for other ideas to this issue and how we can test more to find this issue.
Also - has anyone ever heard of aftermarket HiDs causing these sorts of issues?
Appreciate the input guys.
