JTD 140 Boost fade
been having an issue that is slowly getting worse, on part throttle I get boost building then after a few seconds, the boost fades and power drops, then builds back up again and a puff of diesel smoke appears (when the boost magically arrives again)
On full throttle doesn't seem to be as bad at all, maybe a tiny bit less power ?boost related?
Has anyone else has similar problems / Boost Solenoid / MAP related with similar symptoms?
- Have replaced EGR, and MAF, the Boost solenoid measures 16.5 Ohms - way out of the specified 28.5 Ohms +- 1.5 range. Had been mounted very low and had boost problems in flooded lanes / big puddles.
- MAP sensor was replaced with OE spec HAAS part (eurocarparts) but the sensor had a fault from new, so unsure if the MAP is to blame (p0235 error) - being returned this week at ECP , ideally refund or exchange
- Have ordered a new Boost solenoid which is close to spec, and hopefully will be alot better.
