After being fobbed off with loads of incorrect diagnosis i am at a crossroads with my Mk7 85PS transit. Symptoms are or were eratic tickover when cold, but more worrying is it sometimes going into limp mode. It feels like its running out of fuel, no warning lights or noises, just loses power and the harder you accelerate the slower it goes. its perfect upto 1500rpm just before the green zone, then can either boost slowy to 2500rpm, or boost normally then suddenly cut boost and slow down. the van can be fine for a week, then one day do it every single time i drive it. sometimes you can reset the ignition to clear it and its fine, other times it makes no difference. No fault codes show, its had a new EGR, new MAP sensor, new MAF sensor, and its becoming a bit tedious now let alone dangerous, with often seems to go slow on the motorways. I know it had a ECU upgrade and forced re-learn / counters reset, it made no difference. So anything else worth looking at myself ?
