Warning light - VW Golf 1.4tsi petrol

corklad32

Hi lads,

Had my NCT test this morning and passed fine - however since i left the place my exhaust system warning light has come on? VW golf 08. Is this very unusual? I presume its to do with all the shaking of the car they do. My mech reckons VW's & Opels are very susceptible to this and the light should knock itself off after a few days?

The chances of the light being due to anything that the NCT did is microscopic.

And it sounds like your mechanic wasn't arsed to check what actually caused the light to come on.

Well the car is 4 years old - the light has never come on before - i leave the NCT centre and 5 minutes later the light has come on..... Coincidence much? So I would say it is extremely likely that it was the shaking etc that is carried out in the test that caused this and all I'm wondering is have other people encountered this? As I said my mech mentioned that this is a common fault with both VW's and Opels going through the NCT and i'm wondering has anyone out there had this issue?

When you say mechanic, do you mean a proper garage, or is it just a guy who knows something about cars?

corklad32

An indy! Services cars every day kind of dude.

You realise, I'm sure, that the plates that test the suspension during the NCT test on only apply the same amount of vibration that your car gets during a couple of minutes on the road.

Also, you call it the 'exhaust system warning light', so presumably you think that shaking the exhaust caused this. The light is sometimes called an emissions light but is, in fact, and engine malfunction light. Its a coincidence for sure, but your car has an engine control system fault which needs to be diagnosed and repaired.

Have codes read, take it from there.

If by shaking you mean suspension test, trust me - Your car gets this every day in way more severe level while driving on regular roads.

The emission light could have come as a result of high revving your engine which he had to do during emission test.

Would you ever highly rev your engine during driving? (to the red zone)?
Is your car diesel or petrol?

If its petrol they only rev it to approx 3000rpm which is what most cars are at on a motorway.

Na - I never rev it more than 4 or 5000RPM. Its a 1.4tsi petrol. The joys the joys

So that cant be the case so. They wouldn't revpetrols more than probably 2500 - 3000 for emissions test.

Ehh no I just though it was a diesel.

It is not exactly unusual for a 1.4TSI to have an engine warning light come on. It will have nothing to do with the NCT anyway, that is for sure.

Sounds like your mechanic has neither the interest or the specific knowledge of the 1.4TSI to fix your problem. You need to take the car to someone who is familiar with the TSI engines as they have plenty of common issues that can cause warning lights to come on.

dr.fuzzenstein

As said above, without the specific code, it could be anything.
Engine fault codes are your friend, they tell you exactly where the problem is most of the time.
I don't know why people are so afraid of them!
No code, no can help.

So can we change the title of this thread now then?

Is it 125 BHP single turbo tsi or super charger+turbo tsi?

corklad32

Its the 140bhp one - it has the super & turbo chargers....

I'm going to wait until later today / tomorrow - I had the tsi 170hp model before and that light came on after the VW dealer disconnected something in the engine and reconnected it. That particular time the light cleared itself almost exactly 24 hours after it first came on....So here's hoping hmmmm. Rang another dealer y'day - they didn't pay much notice to it either once the car is running well and not misfiring. Just said drop it up towards then end of the week and they'll have a look at the codes.

a 1.4 petrol golf? dude get used to it, you're going to be seeing a lot more of this light as the car gets older

What? I had a 99 1.4 Bora 8 years, never gave me a days trouble in the engine department.

Central locking on the other hand…:rolleyes:

Lets just say its many years since 'Made in Germany' meant actual quality(as opposed to perceived quality) and bullet proof reliability.:(

Well I was away for the last while so finally got the code read today - p3008 - my mechanic had never seen it before - from goggling it it appears to be related to the camshaft position sensor. Anyone any advice on this? It seems to be driving fine from my limited knowledge but the light is on for a week now. As i said earlier it came on after leaving the NCT. Could the sensor possibly have come loose or moved slightly during the test?

Thanks all

Unfortunately I would say you are going to need a new timing chain

Op do you mind me asking is it a red 08 TS one your driving?

The only way the engine in your Bora and the engine in the OP's Golf could be any different is if one was a Diesel, I really wouldn't put any weight in the reliability of your Bora in relation the OP.

I wasn't replying to the op

Eh gods is that a big job? Bigger than a timing belt? I wonder is it ok to drive for now.

had this car, and had the same problem, put my foot down on a wet road without the esp on and the vibrations knocked out the camshaft position sensor, if you take off the engine cover its like a plug with a lead that goes in vertically. It probably came loose, car wouldn't start for me until it was back in. Once i put it back the light stayed up, you just need to get it cleared.

this is what it looks like
