My saab 95 1.9 tid revs fine in neutral when put in drive and pull of there's no power won't go above 3000 ram any ideas


HI Derek.

There are a few possibilities that come to mind.
3K RPM is generally about the break-even point for when Turbo boost would kick in. There is a dump valve on the turbo system that opens up and vents the extra turbo pressure under high-rpm situations where the boost isn't needed - say high but steady speed on a freeway. If the dump valve system is malfunctioning, then that anticipated turbo run-up in power won't happen.

Revving fine when in neutral may not tell you much, other than that the engine can rev. The gating system will (or should) run differently under load - whether climbing a hill or accelerating, this is where you want the turbo boost to give you the extra power. THat's where the exhaust gate should stay shut, or mostly shut, to allow the turbo to force more air into the pistons.

You might want to check whether the APC (Automatic Performance Control) for the turbo has a separate fuse. (The name might be different on your model, I'm remembering from my 80s/90s era Saabs). If the fuse is blown, that could also lead to lame performance, especially as I'd imagine that the system would be built to fail or go to full open if the APC fails or loses power - that'd keep people from having run-away power that they can't manage.

Hoping this helps

In my Tiguan 1.4 TSI, 2010 I hear a short whistle sound while press a sudden press on the accelerator (Not the normal Turbo charger sound), VW dealer confirmed requested to change the water pump which...


I have the same whistle sound, too.. since last year... just after warranty period. I've notice it comes from the clutch of the compressor that helps the engine until 3000 rpm when the turbo goes into the action. to replicate the sound, check left side of the engine, put someone to push the clutch pedal and then press on the accelerator. Check with VW if there is a solution, although I think you will run thousands of miles and no damage because of that.

I have a 2005 VW Passat TDI140 and recently it started tripping to low power when towing my caravan. Switching the ignition off and on reset the problem. However it repeated say 6/7 times during a 200mile...


However you have not mentioned the miles done on your Passat. If you have done the sceduled mandatory service the engine must not loose out on power when given a larger load. However it seems as advised that when the load is required your turbo seems defeated not giving out the extra power. If possible you must take a second opinion if the turbo action can be checked with a lesser cost of service. Also please check on your caravan wheels for any signs of drag, check on tyre pressures, check on fuel type used. Hope I could help. Good day .

Engine pulling at 3000 rpm and above. Once it gets to 3000 rpm it feels like something is pulling it back, releasing, pulling back again and so forth.


Sounds like a turbo problem, check all electrical connections and vaccum hoses, any engine lights on? Then it's time to take it in, I assume you have a good VW expert just around the corner who is honest, reasonable, and reliable,,,, sometimes it happens! Hope this helps, and look into it right away, it can cause other problems if let go $$$$.

Engine Quits at 3000RPM


Sounds like the dealer is shooting in the dark at your expense. If it was the O2 sensor, it would throw a code. Ofcourse, Fords drivability diagnostics was bad back then. I don't remember exactly how the ignition is set up on them. I would be looking at the trigger sensor for your ignition and ignition module.
