2000 1.9 SE TDI - Acceleration problem. - irishmist
I have had this car a year and over the last two months it has started having acceleration problems. It doesn't seem to be able to make it past 2500 revs and on steep hills it vertually looses all power. On the flat the car still accelerates easily to 90mph but makes its own mind up if and when it will accelerate. This has become dangerous when trying to pull out onto motorways or overtaking vehicles at 60/70mph because I'm never sure that it will make it. The car should accelerate really quickly and my husband is pretty nifty with fixing problems if anyone has an idea of what it could be.

Had similar problem, first will have to ask some questions,
1, what is cars milage
2, is it regulary serviced (with correct oil)?
3, on idle can you hear a whine raises when accelerator is pressed?
4, do you know if the mass air flow meter has been changed?
5, do you drive it hard? (big acceleration high revs)
also you can check the pipe that leads from the air filter box (if you dont know it is the box next to battery passenger side)
look for a tar like residue if there is a lot try to clear it, the mass air flow meter is there it is the plug like attachment with wires coming from it be carefull of it!


look at these things n let me know.

Thank you for your help. We have recently had the air flow meter changed as the mechanic thought it was that but that hasn't done anything. When the car is cold it runs fine but as soon as it is hot it won't go above 3500 revs. My husband is going to check the other bits you mentioned and I'll get back to you.

Does the engine management light come on when it loses power?

What's the 3-letter engine code?

I recently had a similar problem .. but on my 1999 110bhp Tdi .. there's a ball shaped reservoir with a thin hose going to the inlet ...the hose can fracture on the joint into the reservoir ... when it's cold .. the joint is tight, but when it warms up, the crack opens up and lets in air to the system which makes all the sensors read wrong, and put the engine into 'limp home' mode.
Don't know if this is any help on your car?

If you cover no more than 100 miles per day and have easy access to a charging point at home or work, then an EV is ideal for you.

Is an electric car right for me?
