alank Posted December 15, 2021 Report Share Posted December 15, 2021 http://t-design9.com/PDK_distance_position_sensor_7DT45_7DT70_7DT75_porsche.html http://t-design9.com/ppm_tdesign.gif Distance / Position sensor unit for PDK gearbox Exclusively developed by us for Porsche transmissions 7DT45 7DT70, used in 911, Cayman and Boxster since 2009 (models 997 991 981 718) Request Purchasing Info Repair your PDK instead of buying a new one! The distance / position sensor fail is usually indicated by 1731-1735 and other 17xx errors. Previously this kind of error required a new and very expensive PDK transmission. But now it's a relatively simple repair for an indi shop working on transmissions. Please contact us with your specific details to make sure that this is the part you are looking for. Diagnosis: - Car is undrivable or in limp mode - Dash message "Gearbox fault..." - OBD codes 1731,1732,1733,1734,1735 and some 17Dx - OBD errors "Shift rod N displacement sensor" - Dealer/Shop diagnosed "distance (or position) sensor failure"http://t-design9.com/porsche_pdk_displacement_distance_gearshift_sensor_5.jpg The distance/displacement sensor is important part of the Porsche PDK gearbox. It's function is to tell control unit where all 4 shift rods are at the moment. Gearbox control unit constantly communicates with sensor pack to make sure gear shifts occured correctly. Once the sensor goes bad/dies - control unit can not continue. So it will keep driving in the gear currently selected, will not do any more shifts, and after car stopped - it will not let it drive again at all.

Paul P Posted December 15, 2021 Report Share Posted December 15, 2021 Thread on pcgb forum with 911 owner using this (I think). Last time I looked still having a challenge in getting the gearbox to calibrate after fitting. hope they get there in the end. These things may be expensive but they should be fixable.

daz05 Posted December 15, 2021 Report Share Posted December 15, 2021 Simply too expensive when you can pick up pdk boxes all over the country and change them over in less time. You need to create tools to even open them up. Quote Link to comment Share on other sites More sharing options...

If an Indy can work it out and do it substantially cheaper than a replacement they will end up with reasonable business I imagine. Quote Link to comment Share on other sites More sharing options...

They wouldn’t touch my PDK in the early part of the year as they couldn’t get parts for it. Austrin gearboxes were very helpful and I had a lengthy chat with them about the issue. Porsche no longer supply parts to third parties for the PDK box. If the OPC can fix the box in house then i guess it may be possible to buy the seal or gasket from them but nobody I spoke to(and I spoke to a lot)will touch the PDK box as they can’t get parts for it. I spoke to one gearbox repair company who were prepared to take a look but only after I signed a disclaimer to say that if the farked it up they wouldn’t be held accountable.

bandit_287 Posted December 16, 2021 Report Share Posted December 16, 2021 (edited) 2016 car 13,000 miles, one previous owner and fpsh. It wasn’t under warranty I had to fight for it. My thought process is that the PDK box is a bit like the IMS issue on earlier cars as If it fails your car is a brick and it typically needs replacing and if not under warranty you’re looking at anything between £8500-£16,000 for a replacement. It’s not as uncommon as people think, if you do some research you’ll find there’s been quite a few PDK boxes fail and need replacing, four that i know of on this forum in the last year or so.

daz05 Posted December 16, 2021 Report Share Posted December 16, 2021 @bandit_287you replaced yours with a salvage box, what did that cost in the end? @Stuno1you've brought a lot of fear and worry to this forum since you joined the party. Do you work for a warranty company or a rival manufacturer? 🤣🤣🤣 However, today I heard about a friend who lost his engine on a Cayman at around 60k, he's bought it second hand from an indy a while back. He's got a horrendous bill on his hands.for a replacement engine The failure seems to have stemmed from use of the car with an intermittent valve lift solenoid issue. Hoping to catch up with him soon for the full story. Quote Link to comment Share on other sites More sharing options...

Just part of my process so I can weigh up warranty or not, Indy or Porsche, make sure I am aware of potential bills etc. Quote Link to comment Share on other sites More sharing options...

Stark9 Posted December 17, 2021 Report Share Posted December 17, 2021 So my gearbox on my 981S went 2.5 years ago at about 80,000 miles and was out of warranty. It was temperamental and I managed to get Porsche to do a 111 point warranty and pay them £1100 for the warranty (yes I had an Indy reset the fault a few times before they saw it!!) and then a month after I called them and they replaced it. Before this I called 20 gearbox places and nobody could do it. If an Indy replaced it, it was £8000 and if Porsche did it was nearly £12000. Thankfully the warranty took care of it. And 2 weeks ago, after 5.5 years and 130,000 miles, I said goodbye to it. Apart from the gearbox, it was perfect. 1 Quote Link to comment Share on other sites More sharing options...

Austrin gearboxes are fixing mine. They had an initial look over the car - I called 4 or 5 places closer to home and no one was even interested in looking at the car. Then they called me and started talking about seals and stuff. I wasn't really listening very carefully because I was thinking this is going to be bad news so I just asked - Can you fix it. The guy said yes. They are 180 miles from my house so it wasn't simple for me. Hopefully its a good result at the end. 1 Quote Link to comment Share on other sites More sharing options...
