Replying to: sammyh (Feb 11, 2009 3:14 pm) A good one if you are planning on stopping there hp/torque wise is the Sachs V6 SM clutch. What is tricky is the lighter flywheel. Stay with the 20# not the lighter flywheel.

#2416 of 2482 99 beetle tdi power loss by johnzonh Mar 22, 2009 (7:06 am)
hey there,   Im at a loss on this and its something that popped up about a month ago.   our 99 TDI Beetle has absolutely no get up and go.... and will top out at about 70 mph flat highway. I was thinking fuel and air so I replaced fuel filter and air filter...   I'm not burning oil, engine sounds good, no jerking or anything like that. It just will not perform. Starts fine (replaced glow plugs last year...of course got soaked for the job for VW to get rid of the check engine light. We live in relatively cold climate but have had no starting issues and have been through a several tanks of diesel.   The light is back on ...and of course now I am stuck driving slow. Wondering about a waste gate issue? Anything I can do before I go kicking and screaming to VW?

Replying to: johnzonh (Mar 22, 2009 7:06 am) I would bet money that your intake plenum is plugged up... this is KNOWN to happen to MK4 TDIs. The combonation of crappy USA fuel and ExhaustGasRecirculation cause this to happen.The only real fix is to remove the plenum and clean it. It is a very messy job...lots of black goop.   If you do some research about this on the internet, you will find several do-it-yourself cleanings complete with photos.

Replying to: johnzonh (Mar 22, 2009 7:06 am) Possibly the mass air flow sensor, as earlier reply suggested. I had a problem at 80kmi which was sluggish acceleration (low torque), like the turbo quit. Changed the MAF sensor and it was back to perky self. I did not find a max speed as you did, just took forever to get there. Lower gear helped.   I'm wondering if you have a obstruction in the fuel supply (tank vent??) that limits the fuel flow and therefore the speed. Can you find a flat spot in lower gears at same rpm? If so that would suggest a fuel supply problem. Replies to this message: johnzonh (Mar 23, 2009 10:43 am)

Replying to: pludlow (Mar 22, 2009 4:13 pm) oooh ok now maybe we are getting somewhere. hmm. I will look into the intake and the sensor issues.   I didn't really find a "flat spot" ...but if I ever need to step on it, go up a hill, or go flat beyond about 70 it will just not do it. Thanks so much ..everyone for the input. I was really getting worried. in this day and age...getting 50 mpg is like gold. I really enjoy the savings.
