Here's a link about false abs activation which usually happens at low speed. https://www.motor.com/wp-content/uploads/6_BrakeShop_1016.pdf

Hi, Sierrafery, I suspect the latter (Brake in balance) as nothing has been changed in the last 2 years, this fault has just started today. Brake discs and pads were done 2 years ago but we do a very low milage and they look fine, but could probably do with a quick clean-up slides etc. could be...

Hi, Just as the disco comes to a stop (1-2 mph) the abs pump starts (vibration on pedal) I suspect a sensor or sensor plug. the disco is on tarmac and moving in a straight forward direction. I thought the abs was inhibited from activating under a certain speed. so could it be something else. Thanks

Hi, I understand but I need to establish communication for any future faults which I no doubt will be many:rolleyes: If this fault could be slabs related. Would any water entering the rear suspension airbag compressor box cause it.

Hi, Yes the abs light went out after a short run. At the moment all lights are out and everything appears normal. When we connect the diagnostics to the abs module a communication is established and module info is reported (serial No. Etc.) Its only when we start live data and start receiving...

Hi, Discovery 2 td5 auto (2004) using Lynx software. Apparently after driving through the puddle all was ok till we got home, all the lights on the instrument panel came on the second the drivers seat belt was released. (engine still running) the abs light stayed on after a ignition cycle, so...

Hi, Back again, in the middle of all the other issues we now have a abs fault. Light came on, but there were no fault codes. Pulled up the live data from all 4 sensors, set away down the road got equal readings from all 4 then we lost communication with the module. Reset the diagnostics and...

Hello Again, for those of you that have been following this thread, this is what we have done using the advice given. Clean Oil from ECU Plugs Remove turbo/intercooler pipes and check for de-lamination Renew wastegate Modulator valve and vacuum pipes Clean MAP, MAF Replace Air, Fuel, Oil...

No, just wasn't sure I could rip it all out. :oops:

Engine Serial No. starts with 16P

Hi, Its a 2004 facelift TD5, EGR has been removed by previous owner

Hi, Does anyone know what this is (see photos) Wires are disconnected, pipe goes to vacuum and one to air filter .Thanks

Hi, Sierrafery, So are you saying you need to have it connected to the wastegate and then tension the rod compressing the spring to achieve the correct pressures. a pressure of 20.6 psi should be fully extended, do I need to worry about the crack off pressure Thanks

Hi, As part of an ongoing diagnostic I was looking at changing the wastegate actuator, genuine are over £300 if you can find one, cheap ebay about £20-£30, When the cheap one arrived I bench tested it and it cracks off at 3psi and is fully extended at 14 psi. my original one cracks off at 15 psi...

Hi, apart from changing the filters, I agree that what you suggest about Air flow could be the problem, at the higher revs were not getting the throughput. (low MAF) so I'll work on this first and let you know the outcome. Its one of those problems that don't show up on a normal run so we have...

Hi, I'll do that on the next run, I forgot about that, I get then filters done as well and let you know, Thanks

hi, dc volts is 14v + when alternator running, but the air filter is due to be changed which Ill do shortly = fuel.

Hi, I was also thinking cat blockage at the higher revs, would that explain the low MAF readings, how do you know if the cat is blocked? would this not show up when not towing?

Hi, Good advice but we do climb at a steady pace, and avoid gear changes trying to keep the revs at max torque, 3000 ?? I'll try and describe this a bit better so you will understand what's happening. When we hit the bottom of the hill we'll be locked into third gear and remain in that gear all...

Hi, We do always lock it down into third to avoid the box changing we also try to keep the revs a 3000 when climbing, there is definitely no rev increase. its the surging is the only reason why we noticed there was a problem. I'll try climbing in second at a lower rpm and see if it still...
