Power loss

[Pugman406]

Hi guys,

When leaving work tonight, i noticed my car had lost power, was putting my foot down thru all gears, but it was taking ages to shift, i thought maybe the turbo was goosed, but after nearly arriving home , i changed down a gear and gave it sum welly, and it came back to life again.

Has anyone experianced this or know what may have caused it?

Thanks in advance

Hi,I have experienced something similar with mine,also a 110 HDi.This might be
a faulty injector or early signs of pump failure.

If the power loss is in the rev range before 1900 RPM, then it is possibly the MAF (Air Flow Meter)

If the power loss is between 1900 RPM and 3000 RPM then it is possibly the turbo failing.

If it is continuous power loss then check the injectors and fuel pump

Im not to sure but i reckon my vauxhall vectra had a heating system to stop the diesel from thickning up in cold weather i dont know if its true or not dont know if that any help to you or it could be the air flow meter my old vectra did the same loss of power and it was the air flow meter it was a common problem with vauxhall bish bash bosch

On the old TDi , the turbo kicks in around 3000rpm. Find a suitable stretch of road and rev it up. As it goes past 3k you should feel the turbo and the engine suddenly go like a frenchman threatened with a bath. If not, turbo is a suspect. Haynes manual for HDi ought to indicate at what engine speed your turbo hits full load.

If you're keen, you can pull the injectors and post them off to a specialist to be inspected/refurbed/reset. Will cost, but a good upkeep procedure... will do this myself when I can afford it. I miss the injector test rig on the ship. Meanwhile, if you haven't already done so, try dumping a load of diesel cleaner through the system. There's a thread around here somewhere on the subject.

Shouldn't worry about your diesel waxing up unless you're arse deep in snow and it's well below zero. Not so sure about the HDi but the TDi has a heat exchanger under the filter to ensure the fuel is nice and sloshy before it's injected.


Someone please correct if I'm talking out of my wastegate ^^
