    Question Emmision warning light - fault code

    Hi,

    I have a 2006 2.0 TDI. Apologies for the lengthy message but i could do with some help...

    My emission warning light has been on for about 2 weeks now (although I have not noticed any difference in performance). I'm currently doing a lot of stop-start town driving and I read on this forum that sometimes the DPF can get clogged so I took it out for a longer motorway run but the light remained on.

    I then booked it in at my local garage who hooked it up to their diagnostic system and read the following fault...

    '12547 motor for intake manifold flap (V157) malfunction P3130'.

    They said that if the flaps need replacing one was approx 400 and the other was approx 500 (both +vat & labour) but they could not guarantee which it would be.

    I wasn't keen on the bill for either let alone both so they suggested that they clean it out. They removed the 'inlet manifold' and 'throttle body', both were full of carbon and the seal on the actuator was split so they 'removed the control actuator, refit seal correctly with sealant', cleaned carbon from all parts and refit. They test drove it and the light went out. When I collected it the light stayed off for a day but then came back on and has been on since.

    Does anyone know if there is anything I can do to fix this avoiding a huge repair bill?

    I had a similar issue with my V6. If you take it to Audi they will know which one (or both) have failed.

    I did a load of research and although cleaning sometime helps for a short time it doesn't resolve the issue. I think I paid around 400 all in from Audi (including being driven to and from work in one of their cars, car wash, a couple of cups of tea and some nice biscuits) Who says main dealers are expensive? In comparison to what you have been quoted that's a bargin.

    Ok thanks for your help. Might go down the Audi route - just assumed they would be more expensive.

    Do you know if continuing to drive with the light on can cause any damage? I've not noticed any change in the perofmance of the car.

    Depending on the exact issue the flap issue I had is designed for anti shudder so I had low risk for further damage. I would always get things fixed as soon as possible as you cannot be sure until you have the exact fault details.

    Also, yo umentioned DPF.

    How can you be sure your car has one fitted?

    My 2.0TDi BRE engine in an 08 car does not have a DPF. Audi swore blind that it did but if you look in the workshop manuals, you can clearly see that the only thing my car has in the exhaust is the CAT!

    Also, the intake manifold flap could be dirty or actually broken. YOu could take it off and clean it and see if it looks OK?

    They are not hard to change.
