Reamed well and truly chaps. Was taken to a main stealer hence the bill. And just for clarity 'well spent' was said with the greatest irony!

Figured it was worth pish all as a non runner so I sucked it up and sold it almost straight away. After the new engine and a catalogue of other failures that really was the final straw.

Regret it now a bit. Was a Holland and Holland.
 
Jesus.

We rebuild becm's for a lot of garages & main dealers who order them 3 or 4 at a time.
I have had their customers approach me over the cost involved as they include my invoice with their own paperwork when the owners pick the vehicles up. They copy my invoice without any figures & I'm shocked at how the price is topped up by a grand or so.

It's just so unneccessary.
 
Live and learn. Notch it up to experience. Everyone makes mistakes but only a fool keeps making them.

How many P38s have you had? :)

A good point well made! Enough to learn the lesson now. 300tdi Soft dash. Yes, I have to keep on top of welding - although have taken to replacing rather than patching now - and yes it's clattery but simple and mostly easy.

And it has a charm all its own.

Just to really make you chuckle of that £1600 £270 was 'diagnostics'. Yep. £270 just to tell me I needed to spend more. Hand on heart that's the last time I took a vehicle to a stealer. Burned my faith they knew what they were doing and offered the most professional service.

They don't.
 
Had a conversion with another over the BeCM. Seems there are some right diabolical merchants with the white hot soldiering iron around. I must flag up my regards to the Brighton man :) Straight forward and Ex REME as well. Arte et Marte. Sorry to the bootneck as well from a pongo. I too had the demon french LHD etc. Nanocom and now it's RHD and all correct. Always listen to them in the know. :tea: When in doubt brew up.
 
No hopefully soon as the boxes arrive, I will use the time to check other links from the BeCM. I have read some BMW forums on the engine and it would appear the engine ECU's are prone to problems, mainly water ingress. I couldn't see any water marks inside the black plastic surround and the ecu was not tampered with. I will await the outcome. I could do with it, I have a funeral coming up later this month. Do not worry we will let the results be known.

The ECU box looks pretty watertight to me. Mine is still bone dry and it doesn't quite seal properly because of the extra wires for the hotfix.

Sent you some stuff on the ECU.
 
Roger that, I have just spoke to Rick and IT'S ALIVE !!!!
I will post a full run down on the whole thing.
Now I believe it was the Diagnostic machine at the test, caused RF interference. But I will not know until the next time I go there. Thanks to all and full run down later. Now I have work to do finishing off the refit before the thunder.
 
Ok, Beginning of problem was,starting the car, delayed starter, not a unit problem, more like a immobiliser delay as the key turned to starter position, later a misfire at the MOT test, then driving back, lack of throttle response. Next day, engine turning not starting. So plugged in the kicker, sync the boxes and green light on kicker, turned over still no joy.
So nanocom plugged in, select EDC. faults read. Low fuel flow, immobiliser fault. faults cleared. Engine turned same faults appeared. So found tank pump gone, ordered a new one and went about trying to fit it. Pump fitted, using a bridge on the pump relay, bled to the F I pump and tried to start. after a lot of bleeding, including the BMW proper procedure and not a fart. Must be a ecu problem, so tested all the feeds and outputs from the ecu, CKP sensor was suggested by one specialist. I tried the sensor and read the specs all in line. So not the CKP sensor. Another search amongst the net and the RAVE disc. after reading a lot on Diesel systems , I found a paragraph in RAVE it confirmed my suspicion that the pump immobilisation is down to the "Control Collar" being moved to prevent the high pressure build up and therefore no fuel to the injectors. I arranged with Rick the Pick to test the BeCM and he did find problems with it. Also getting some settings restored. On the return of the unit. it was installed, key synced and on turning the key fuel from the injectors. Tightened up the injectors and it's alive. So despite reading on line, that the only control was the elab (cut off solenoid) these pumps and later ones use a device within the pump to stop engine starting. The system cuts out engine cranking as well, attempts to bypass these will lead to problems. Test drive of 50 miles and several starts since, all well. Thanks to all and Thanks to Rick in getting me back on the road in time for the funeral.

As has been stated many times, the ELAB is only a back up, fuel cut off is done by the quantity servo in the FIP.
 
No messages on the dash, not a indication that a fault other than the immobiliser link low one, and looking on here. Nanocom faults were read and still the engine runs. So I dismissed that as a fluke on the code reader. It ran perfect up to the MOT. Even without the tank pump. I now have increased power and good acceleration, so since I have had the car the tank pump was u/s. Rick said that something had screwed the BeCM. I spoke today with a guy (Cambridge electronics graduate) and he sorted my interference problems with the TV due to 4G phones, I have been to Maplins and bought a filter. Amazing the people you find in the College Arms. I am wondering if it will smooth out the blue wire on the Range Rover. Already got some ideas from him.

Don't keep it a secret, details of the filter please:)

Engine immobilised and the security code are not the same thing. Engine immobilised is a function of the alarm. If the BECM receives an incorrect FOB code or the car having been locked by the FOB is opened with the key the message appears and the car will not crank, the starter circuit is disabled. Entering the correct EKA code or pressing the FOB if synced enables cranking. If the FOB has lost sync, only after the correct EKA has been entered can FOB be synced to car. If the security code from the engine ECU is lost by or scrambled in the BECM. The car will crank all day but will not start, because the engine ECU is not switched on. Your engine will not misfire due to electrical problems, that was more likely down to air in the system due to the lift pump fail. The genuine lift pumps have an NRV in them if they fail air can be sucked in via the O'rings on the filter or via a leaking spill pipe. That would give your misfire, you possibly sent the BECM into a tizzy by flattening the battery trying to start it or by connecting and disconnecting jump leads or chargers. P38s DO NOT like low battery voltages.

RF interference certainly flattens batteries fast! Not sure if it directs affects the BECM other than the low volts though ... although, it does burn the locks so something is getting through and scrambling the BECM.

The battery flattens because of the spurious signals leads the BECM to think that it's being stolen so it relocks the doors and wakes up the alarm. When it realises that it is not being stolen it goes to sleep again. If it's being woken up every 10 seconds then after a time something's got to give.:)

Yes but this thread is not about RF interference. It's about a car that developed a miss fire then would not start. The OPs actions possibly lead to it's demise in all probability. Basically if you don't know what you are doing don't play. :);)
