Thread: My D3 hates Towing

Heck your battery post is tight - the Negative one...

Also check you have the latest software revisions.

Also check that there are no CAN bus connection issues or shorts. Brake switch also might be worth looking too at based on one of those messages (the standard go to solution for cascading errors). Also check your tail lights etc for any dodgy globes, they have been known to cause these sorts of issues when a filament fails and causes intermittent connections (go to LED globes if you can, ~Rich~ has done this I think).

I'm just rereading the list and brake switch/globe look like a potential contender..

Don do you have a chip on the engine? (not a remap).
If so then the following might be of interest. I had some similar fault codes with limp mode triggered by towing ~1600kg hybrid camper with the engine chipped on my previous D3 (2.7L TDV6)

P000E-22:FUEL VOLUME REGULATOR CONTROL EXCEEDED LEARNING LIMIT : SIGNAL AMPLITUDE>MAXIMUM
P00087-00: FUEL RAIL/SYSTEM PRESSURE- TOO LOW
P2299-68:BRAKE PEDAL POSITION/ACCELERATOR PEDAL POSITION INCOMPATIBLE: EVENT INFORMATION

It happened 2-3 times whilst towing under load (up long steep freeway climbs) Removing the chip (or turning it off) whilst towing solved the problem for me. I sold my D3 to a mate and advised him against putting the chip back on if towing. He decided to give it a go anyway and the same thing (Limp mode triggered) happened to him 4 times driving back from Alice Springs to Adelaide! He's since taken it off with no further issues.

Chips belong with Fish and Vinegar..

Only remapping should be done on these engines... And then only by very reputable tuners.

Yes agreed Tombie! This happened in 2011 and I learned the hard way! I would never use one again. David

David I bought the D3 2nd hand and it has lots of a/market extras. It goes like a rocket and no problems towing the cvan up hills. If it is chipped where would I find it and what does it look like. Is it in a "Plug & Play" harness?? cheers Don

Yes it is "plug and play"! Depending on the model it will consist of a wiring harness attached to a small plastic module likely to be mounted near the starting battery (mine was actually inside the battery compartment wedged between the battery and front edge of the plastic box so check in there or just in front of it). The wiring harness will lead to a "T" junction that consists of the original engine plug joined to one end of the harness and the other side of the 'T' goes to the plug on the side of the engine near the common fuel rail - either towards the front left side if a late model D3 or at the back if early model D3.You need to take the plastic engine cover off first though to see this area. I can send more detailed instructions and photos as a pdf file if you PM me. Also if you take close up photos of the passenger side of engine with plastic cover off I could probably tell you if you have a chip fitted. Hope that helps.
