2010 (Sep2009 built) Octy RS TDI problem

[dazag]

Am in need of someone in the Adelaide area that might have a VAGCOM VCDS?? I have a fault with the exhaust system on the TDI RS that i want to check codes on etc.
Had noticed it surging a little at random over the past couple of months, would only do it for a short time, but enough to be noticeable. Then on Friday the Exhaust control light came on. I thought it may have been due for a regen considering we had been doing a fair bit of city driving, but didn't get a chance to go for a long drive over the weekend. The wife said she didn;t see the DPF light come on at all. The wife then told me today the past 2 times she drove it (yesterday/today), it has gone into regen mode and she's had to let it idle to cool down before switching it off.
I've just taken it for a 1 hour highway run and it was doing a regen, but when i got home it was still in regen mode. I popped the bonnet and it didn't seem that hot, infact the egr pipe that goes into the intake was cool, which i thought was interesting. But the exhaust heat coming out the back was warmer then nromal so it is definatly in regen mode.

The car seems to be running fine, nice & punchy, no surging, only thing is fuel consumption is up a little but that's due to it being in constant regen mode. I have a feeling a sensor has failed in the exhaust system and has caused the ECU to think it needs to do a regen. I just need to get my hands on a VAGCOm to check the codes and double check the exhaust side of things to see what's failed, and then I'll go from there.........

See Transporter. He's your man with all the knowledge and tools in Adelaide.

Then on Friday the Exhaust control light came on.

I've got an Octy RS wagon. Mrs. BS has a Golf Vl TDI DSG. For what it's worth, last year her ehxaust warning light came on. She only does short hops, so assumed it was a dirty sensor, or a DPF issue. Turned out to be a failed water pump clutch (new pump fitted under warrant), and nothing to do with the exhaust system itself, or the DPF. Give Transporter a call sooner rather than later is my advice.

The lights on the Skoda have a warning light for the DPF and another light for the Exhaust control system, it was the exhaust control light that came on.
I Am trying to get this sorted ASAP and Transporter is a little booked up, so I might have to go on gut feel....

I've done some research and there is a known problem with the Exhaust pressure sensors (P/No. 03G 906 051A or G) that the circuit card fails. There is a few threads in this forum that go into it. The symptoms they explain are identical to what has heppened with my TDI.
The replacement sensor is P/No. 076 906 051B. Talking with the Skoda parts guys here in Adelaide they reckon they replace about 3 of these sensors a month.......
So will replace it and then see if I can get one of the service centres to quickly do an Adaption process for it and I should be good to go.
I will take a couple of pics so the Diesel guys can see what I'm talking about and can check what sensor they have fitted....

Turn the key on/off 3 times, and it'll adapt in most cases.
