Hi Guys,
I have a 1999 C70 T5, with the ME7 engine and a distinct lack of performance.
Driving down the motorway there is not as much oomph as I remember when acclerating to overtake, nor is the full bore acceleration as quick as it should be.
It feels very similar to my previous car, a V40 T4, which also lacked performance and was restored with a new turbo.
During some previous work, I had removed the heatshields around the turbo and not put them back. So I can hear the wastegate chirping on gearchanges, this does not seem to have changed.
To see what this turbo is doing, I purchased a bluetooth OBD2 dongle and installed the Torque app on my phone. This has shown that the turbo is only boosting to 6psi.
Today I changed the air filter, just in case that was blocked and restricting air flow. No change to performance or boost level.
The car has done 140k miles, 45k of those with me and it might still be the original turbo unit.
What other parts surrounding the turbo itself could be at fault and how can I test them?
Please help, I'd rather not splash out on a new turbo only to find it is some of the control parts next to it!
Alex.
