Hi All
Loving the forum. Who needs a haynes manual when we have a resource like this.
For those who haven't heard my limp mode woes I'll start at the beginning
Van is a 2007 T5 4motion 2.5 BNZ Engine 140PS
Problem started about 6 months ago. Intermittently going into limp mode, about every 100 miles. The problem usually happens early in a journey, and usually at the top of a hill. It can be reset on the ignition cycle and then the van goes back to normal. I do 100 miles a day so see this problem nearly every day and I'm falling out of love with my van a bit now!
I have been to my volkswagen trained independent mechanic a few times with it now. He said VAGcom logged an overboost code each time and suggested it was either turbo or n75 valve. He changed N75 valve, no fix. He replaced the turbo with a garrett one, no fix.
I have just taken it back in and got the code off VAGcom, it's P0299 Control range not reached. I said that is underboost, surely. He claims it was a different code last time.
I have suggested a pressure test of the charged air system for leaks would be the next step, do you have any other suggestions?
If my guy doesn't fix it this time I'm gonna go elsewhere.
Any suggestions
1) For things we can try while it's still on the ramp.
2) For garages/mechanics near Radstock, Bath who may be able to help me.
Cheers
