It's all gone a bit Peter Tong
Took the Z out today, had a brilliant ride out, pulled into drive and switched off. Thought I better put electric roof up so restarted engine. It was like the flight deck of a 747, warning lights all over. I eventually got it started and it runs like a bag of crap. I have no idea what the problem is, I think I'll have to take it to a specialist, unless you know different ??
Wow, that took a bit of reading Titan. There could be something in that as my alarm has bee playing up for weeks. It goes of if I use the key fob but not if I use the key !!Titan wrote:If it's not the battery terminal connector (which is very plausible) it could be chaffing wires behind the instrument binnacle.
Have a read of THISthread esp @Guest (Mike Fishwick) 14 October 2008 10:42
Well I've checked the battery connections and what wiring I could get to and all seems ok. The lights that come on and stay on are the automatic gearbox problem light and the dsc warning light. The engine also sounds as if it's firing on 4/5 cylinders? It will start after about 3/4 sec's turning over.
Ok, I've run a diagnostic and it comes up with 2 faults:
P0335 & P0727
Reading up, these 2 are connected ( I think) I found this:
The P0727 code is a universal code, so it is used by most manufacturers, including BMW. Its technical description is "Engine Speed Input Circuit No Signal," caused by a lack of data for the engine speed input circuit.
Engine Speed Input Circuit
The Crankshaft Position (CKP) sensor monitors engine speed, sending its data to the Engine Control Module (ECM). The ECM sends this data on to the Transmission Control Module (TCM). Code P0727 is the result of the TCM not receiving the signal from the ECM.
Causes
The cause could be a fault with the CKP sensor and its circuit to the ECM or problems between the ECM and TCM. In the first instance it is worth checking the electrical connections on the sensors, ECM and TCM for damage, moisture or dirt.
Now where do I find these sensors?

I've been reading through a lot of stuff on other BMW forums and this appears to be a common fault. It always points to the cam shaft position sensor but when replaced it makes no difference. It seems most of the time it's the ecu getting confused. What would happen if I disconnected the battery for 5 mins? Anything? Nothing? Or other problems? Just a though.
I will be taking in to the auto electrician this week if I can't find an answer.

Crankshaft sensor is at 10 o'clock (radiator, fan, water pump pulley and belts removed)macca wrote:Now where do I find these sensors?
I'd check the connections. If all OK, I'd remove and test with an analog ohmmeter by passing a piece of metal through the gap and look for a pulse.
But then again, I'm a skinflint who would spend three days fixing a £5 watch .

Right, I took the Z'd to a local indi (never used them before and never will again, read on). I took it in 8 days ago and they said they would run a diagnostic and find out what the problem was. I told them I had already done that and told them the faults and codes. Yes but we have "special equipment". They rang me later and told me exactly what I told them!!!, that'll be £35 + vat then please. Ok say's I, now fix it. After several visits and phone calls to them through the week, they had worked on it a grand totally of 1 1/2 hrs. I told them they have 2 hours to find the problem today or I will remove the car and not pay the bill. 2 hours later, phone rings "hello, we've found the problem, a loose connection on the gearbox and a duff camshaft sensor" that'll be another £375.62 please.
What kind of fault finding do you use I say's, considering the faults said faulty camshaft sensor and no communication being recieved at the gearbox and it takes you 3 1/2 hrs to find them???
These kind of people rip the non clued up people off. I have to pick the car up tomorrow night, I can't wait to talk to the owner and tell him what I actually feel about his ranch, sorry I was thinking about cowboys then.

Picked the car up tonight and asked to see the old sensor they replaced. Ummm, we can't find it, it must have been put in the "burn bin".
Ummm, very convenient.
Where is the exhaust cam sensor located on my Z'd so I can check they have changed it?
Sorry for the moaning, but I hate shoddy customer service as I actually work in that type of job.

I don't see why they should get any sort of protection from loss of business, they certainly don't sound like a place where I'd want to take my car. I say name and shame them!lebigmec wrote:If you don't want to post it here for all to see, please PM me, if you would.

Location of Exhaust cam sensor. Open the bonnet. On your left hand side see the top of the engine closest to the top of the radiator. Run your hand (palm towards the engine) across the top front of the engine just there. Your fingers should find a wire. This wire is plugged into the Exhaust cam sensor.
It will be difficult to detect if it has been replaced. A mirror might help. Best of luck, hope this helps.

Thanks, I'll have a look tomorrow.Mr Silver wrote:Location of Exhaust cam sensor. Open the bonnet. On your left hand side see the top of the engine closest to the top of the radiator.

The trouble is I can't prove anything yet so it could be classed as libel !!XVar wrote:I don't see why they should get any sort of protection from loss of business, they certainly don't sound like a place where I'd want to take my car.
