Tame Technician or any other Tech, please help with my A8
Discussion
Hi, I have a 2005/6 A8 3.0tdi with 135K on it. For the last few months the ECU warning light has been coming on intermittently and the car had a strong smell of fumes (a really acrid, overpowering smell)
• The car now gives a lot of white smoke in traffic and if I rev the car at idle.
• It does not seem to give off any smoke under load. The performance and fuel consumption seem normal.
• The ECU light in now permanently on.
• A local garage did a diagnostic and a code relating to insufficient flow came up.
• They checked the EGR and it was clean. They performed a pressure test and functioned correctly.
• All the pipes were clear except for the EGR pipe where it comes back into the throttle body. That was badly clogged. He cleaned it out. The car ran a little better, but the ECU warning light stayed on.
• The diagnostic was re-run and it is now suggesting a faulty throttle body.
Before I fork out for a new throttle body, has anyone got any experience of these symptoms or thoughts on what it could be?
Thanks in advance,
Rog
