Thread: My D3 hates Towing

Don, out of curiosity I had a sift in Disco3 for your fault codes, particularly P0087 and P2299.

P0087 could be related to a fuel pump or fuel filter issue but if so, is usually associated with P2290, which seems the more common code and you don't have that one.

However, P0087 has also been associated with the brake pedal switch issue and this cause would line up with your P2299 code.

So if it's not related to a chip, then the suggestion of changing the brake pedal switch and checking all brake bulbs is worth doing.

Thanks Scott. There is no performance Chip and I found 2 blackened brake bulbs . Brake switch working ok as it signals the Brake Controller for the Caravan.I am not sure of the lineup of the signal to the brake controller as it was fitted by previous owner. I always double relay the brake switch signal with polarized diode within the relay to protect computer circuits. cheers Don

Well that's the first thing to rectify Don. Regarding the switch, it seems that when faulty it is intermittent so may not affect your brake controller in an obvious way. Also the recommended way to wire the brake controller signal is spliced to the stop light wire rather than brake switch. Not sure if that's relevant to your problem though. Hopefully it's the bulbs.

Thanks for help guys. When we were on the road last week was afterdark and 2 separate cars dooted the horn and flashed headlights behind us and we took no notice, Well today after suggestions I found 2 partially blackened tail and brake bulbs in rear lights which could be the culprit to the Limp Mode (hoping it is) as the tail lights may of been flickering off and on, Bulbs replaced so this Tuesday head off with caravan again.
The other contributing item could be the logic in the brake controller signal wiring. If it is sourced from the tow connection at the back should be ok but was in the D3 when I bought it.

Don, also worth looking at fitting LED bulbs as per this thread. Then you are unlikely to face this issue again.

Given you're leaving Tuesday have a look at Jaycar for them. Or at least take spare standard bulbs with you.
I would be sourcing a spare new brake light switch to carry as well. They are pretty cheap insurance.

Brake light switch is MUCH cheaper from Ford Dealers.
