The brake fluid level indicator alarmed and the fault was traced to a leaking ABS pump. Part # 996 355 755 58.

The mechanic sent it off to a specialist but it's unrepairable. In fact it has two leaks, when tested so worse than the initial diagnosis suggested.

Given the car has 100,000 miles on the odometer I'm not looking to replace with a new part.

Any help the Rennlist team can give in sourcing a used one, and/or advice on part number capatibility would be much appreciated.

Thanks, certainly an option. Feedback and lack of guarantee go with the price, as does mileage.

Are leaks common in this pump i.e. how much risk is there in buying higher mileage second hand?

John McM

It appears that the part has been superceded by 996.355.755.63. Any last words of advice before I buy?

A leaking ABS pump is a new one to me.

A second hand pump may be no better than the pump you have now.

I'm having a difficult time imagining why someone would pull an otherwise perfectly working ABS pump from his car to sell.

The only way I'd be comfortable buying a second hand pump is if seller had a good return policy: If the pump proves to be bad or leaky a return for at least full credit within say 90 days would go a ways to mitigate my concerns.

I think savage yards part out cars regularly.

Make sure you get a good pump as losing brakes at high speed won't be a pretty sight.

Bakes and tires are two things, i don't/won't save money on.

Beautiful car though

The 996TT or the Turbo 3.6 for beauty? The 996 TT is growing on me, but washing the hindquarters of the Turbo 3.6 is an experience....

Bought a used part from a German wrecker. The part came from a 2003 C4s, from which various other parts were being sold as well i Seller has 99.9% feedback on 8,000 + trades. Also has a money back guarantee. As these don't appear to be repairable and/or fail that often and whole car is being parted out, I'm not concerned that I'm buying a repaired dud. Genuine Porsche, likely off a car with fewer miles than mine. Cost was USD 1,000 compared to USD 4,000 new.

Looks like a good deal John. I am often looking at parts on Ebay and the ABS pump is always around a thousand dollars. Good luck with the installation and keep us up to date with this project.

A failed ABS pump will never cause you to lose your brakes. The pump is specifucally designed to not let that happen. So buying a used one is a fine endeavor.

I sourced a used pump from Germany. It came off a 2003 C4S. At 25% of the new Porsche part price it's a risk I'm prepared to take. Fitted and issue fixed.

I have a 2001 996 C2 with the ABS/PSM fault lights coming intermittently on, with error
"P1574: Porsche fault code 364 - Stop light switch Signal implausible"

So far I've changed the brake light switch 3 times, clutch switch twice, ignition switch, checked the brake bulbs, changed the brake pressure sensor on the ABS pump and the MAF sensor has been cleaned. None has fixed the problem. My local Porsche dealer keeps telling me it is the brake pedal switch, but it doesn't fix the problem.

A local specialist thought it was the Bosch brake pressure switch, but it also didn't cure the fault.

I bought a replacement ABS unit off a 2004 996, but the part number is slightly different: 996.355.755.62
(my car is 996.355.755.52)

Is it likely to cause problems or fix the issue if I install this? My Bentleys manual said the pump unit needs to be coded to the correct transmission type (tiptronic or manual) after installation.
Is this possible with Durametric Professional?

I know that I sound like a broken record, but squirrelly electrical gremlins in a 996 can often be caused by a bad or failing ignition switch. $12 part (in stock at NAPA) and 30 minutes of low-tech work to swap it out. Worth a try. Worst case scenario is that you replace a part that's gonna fail on you at some point in the future anyway - ignition switch is a very common failure item.

My car being in storage and having nothing else to do I decided to try to answer your question about Duramteric pro. I went in my garage and plug a PST2 (I do have both , yes I'm a bit mental) and in fact in the ABS menu there is a coding section that ask you to input if it is a manual transmission or automatic….Took the PST2 off and plugged in the Durametric pro version 6. Sadly the only coding I could found was for the instrument cluster. In the ABS or PSM menu there was no possibility of selecting between manual or automatic transmission. I could be wrong but search without any success….

Thanks, I already replaced all the switches, including ignition. I tried the Napa part but the quality and fit was so bad that it broke when I reinstalled it to the back of the ignition barrel. I bought a $30 part from Pelican instead, which was much better quality and fitted perfectly.
