get the part number of the comms 2000 and hit ebay, theres also a ebay seller who can fix some comms units. or i can give you the partnumber for the comms unit if you give me the last 8 digets of your vin number

that would be the tps, it looks like a black boc withe a 4 pin conecter and the accrator cabel conected to it. thay fail becaus the greas becomes conductive thay can be cleaned hears a guide http://306oc.co.uk/forum/archive/index.php?thread-9969.html

have you had moments where you press the accelrator peddel and nothing happens? mafs tend not to post up "antipollution Fault"

this sound like a dirtey fuel pressure regulator . is it a bosch setup?

mike thay have two settings pre and post start, the pre start only comes one at low temps but the post comes on to aid combustion untill the engine is up to temp or reved above 2000rpm.

over-boost would put it in limp mode. it could be a dry wheel bering or many other things

non of my hdi's are useing the glow plugs or start up just post start. the glow plugs are only used below 5c and then its like 2sec, i used to have a littel chart with them and glow plug on time. had an old 8 valve hdi lighting off in -17c and the only problem it had was a bit of white smoke. p1598 its in french but its got pics so it may help http://www.forum307.com/viewtopic.php?p=862647&sid=41bf95747f0ac249e4b3652ca71fd015 it seams to be an electrovalve on the thermostat housing

if your battrey voltage is low it will have an impact on the start stop, it may be somthing compleatley diffrent tho. so check your battrey and then get it on a lexia and check all is ok things to chek are battrey voltage when running and switched off check wiring see if it looks chafed or cut air conditning gas presher (can be done with lexiea) thats about as much as i know about start stop tec but some one will be along to add stuff no doubt

if you are near me then i have deler diag equipment, i am in sheffield south yorkshire.

running on is normaly the fpr on the back of the fuel pump easy to do and cheap to fix

there is a jacking point in the middel at the back just in frount of the tow bar, i can put up a pic if you like.

first thing to try is a bsi reset, if that dose not work then we need to start looking at other things. CORRECT REBOOT PROCEDURE FOR BSI Put the driver's window down, lift the bonnet and ensure all equipment is switched off. Ensure all doors are closed and remove key from the ignition. Wait for 3 minutes, disconnect the vehicle battery and wait 15 seconds. Reconnect the vehicle battery, wait a further 10 seconds (do not open doors.). Switch on the side lights through the driver's window. Switch on the ignition and check system's functionality. Hold lock button on key down for 10 seconds. Remove key open & close door test central locking system. Start the engine and complete the system's check. Reset the clock and date. Failure to follow this procedure could result in incorrect operation of many BSI related items.

drain the tank and put some fresh fuel(the good stuff) in it, don't jump the gun with replacing big parts yet. lexia can do evrething, it sounds like it just needs to be run abit. prime the fuel system befor you start it see if that makes a diffrance i am not shour how to do it on the petrols but on the diesels you switch the ignition on to position 2 wait 10-20seconds and cycel it like that 10 times, also spray some starting spray or somthing that will make the engine speed up and sprey it round the vac pipes and throttle body this will show air leakes. be carful of hot manifolds and flamabul sprays!

the brake pipes don't all ways scrue right in on most of the cars i have worked on its sound like he has not bled the brake fulley you can do it at home takes about 20mins its well documented on youtube. i did it the wrong way round just like most mecanics will and my brakes are fine so don't worrey about that or the abs, as the abs will blead throught as you bled the brakes.

thanks for the update and telling us what it was

High engine rpm, would be reving the engine under load and as close to the red line as you can, but stay with in speed limits

check for a stiff hand brake mechanism as that may cause the pad to be tight on the dist and move when setting off and check and greas the brake slider pins

drop lins would only be going over bumps and unevan surfses, i would be looking at the brakes, wheel berings, balljoints and drive shafts frount and back

well lets start by asuming that the mecanics don't know what thay are talking about or are just not sure about it and ask why are thay saying it needs a new engine? so whats the fault and how did it manifest it self? if its just snaped the timing belt just put a new one one and see, the rockes are desined to brake in the event of pistion contaced so can be replaced if you dont mined a trip over some hills and it will make it you can bring it to he to have a look at i am in sheffield

its the ac compreser clutch or the power stering pump the ac compressor clutch you can spray a bit or wd40 or sume such on it but not where the belt runs get as much as you can in the clutch see if it stops it

it will be a lightly warn aux belt thay are about £12 and you a long 15mm spanner for the the tensioner and an 8mm hex key and a 1/4" drive may be needed for the maual tensioner depending on belt tension

i to will be going led when the bulbs go on my one thay can be changed from the back but i have big hands (90mm at the knukel) so got my dad to do it wich worked

you are all missing the clutch switch which could cause this

there is one option missing from what you have looked at and that is a high engine rpm run (12miles min) cleans the injectors, combustion chamber and turbo infact most things post engine and the back of the valves and its cheper than most of the other optins and works to

so whats been side is that the caliper fixing holes need a bronze bushing fitting to reduce the size of the hole and if a thred is taped and a coller put on the bush it will holed itself together, that sounds like a nice simple alterntive to lock tight.
