Dan. 0 Report post Posted April 19, 2008 Hey guys ..... The E36 318 Ti has been having strange idles on and off .... usually being rough up and down between 500 - 1000rpm .... other time doesnt hapen at all, but when it does hapen like today, travelling aroung 50kms, the car hesitated and wouldnt accelerate, but when i put the gas pedal to the floor it goes away... Have been reading up that it could possible be the ICV (inlet control valve) that needs cleaning. Or checking that the inlet hose from the engine to the filter box has no cracks. Anything else that i may need to look into? Anyone had similar problems to this and got it fixed? and how? Quote Share this post Link to post Share on other sites
sp8s 1 Report post Posted April 19, 2008 (edited) I have the same thing going on. Have been waiting for a day off to have a look. By the way ICV = Idle Control Valve Edited April 19, 2008 by sp8s Quote Share this post Link to post Share on other sites
Yuen 16 Report post Posted April 19, 2008 Seeing that there was a hesitation when the car was actually going, I doubt it's the idle control valve. I would check hoses for vacuum leaks, and use the opportunity to replace any hoses that are old and squishy. Quote Share this post Link to post Share on other sites
*Glenn* 854 Report post Posted April 19, 2008 You will need to get it scanned. Being a TI it will be either M42 or M44. Its more likely to be the camshaft position sensor ( common fault ).......DONT fiddle.......get it scanned first Quote Share this post Link to post Share on other sites
325_driver 422 Report post Posted April 19, 2008 just recently i had a similar problem turned out the rotor and dizzy cap had seen better days and before that i had another similar problem after searching intake hosing i found a nice split in one of the air intakes might help Quote Share this post Link to post Share on other sites

Ill visually check for hoses for the time being but will get it scanned to be on the safe side Thanks Botany Motorworx ...... sorry your name was? lol Mite have to pay you guys a visit Quote Share this post Link to post Share on other sites

Shite!! Our scanner hookup is $40 +GST. As Glen said though - dont play -apart from obvious things (air leaks etc) you are only guessing. A scanner can eliminate a lot of headaches - the joys of a modern motorcar Quote Share this post Link to post Share on other sites

Just a point on defense of the guys who charge for scanning - you have to remember that the machine they hook your car up to cost big $$$$ and usually extra $$$ for upgrades and connectors etc for new models. Certainly from my industry ( Camera Repair ) we recently priced up some camera interface tools ( just for one BRAND of camera ) and the total was going to be over $ 60 K !!! Would take a lot of $70 chargeouts to recover that! Only so much can be 'included' in the labour rates - especially with Four weeks holiday, Kiwisaver, ACC etc etc etc { Rant ends! } :) Editted for spelling mistakes!

I totaly agree with you here I have two scanners one cost $8,000 the other $10,000 Upgrades cost me approx $3,000 a year for both Plus we have 4 wireless computers which have to be maintained. One has 60 gig of technical info which I would hate to loose. We'd be buggered without it....you can't remember everything. One of the scanners is mobile, so that you can read live data while driving ( two people required ) We normaly charge $40 for a scan + $75 an hour for diagnostic time. If its just a scan and report its $40 People just think that because you plug it into their car and give them an answer to their problem ( it might take 5 min) that they shouldn't pay for it Quote Share this post Link to post Share on other sites

It will only read and cancel codes Not much use to us, specialising in the work we do You need live data read outs as well so you can see whats happening in real time. Our Bosch scanner allows us to check a fault and go straight to diagnosis data and repair data. Quote Share this post Link to post Share on other sites

sp8s 1 Report post Posted June 11, 2008 Ok Its taken 2 Months to sort out my idle problems. Lots of people have looked at the Beast, put it one scanners, checks fault code blah blah blah. Finally took it to a company (Craig Gilberts) and a mechanic that specializes in Mustangs took a look at it played for 10 minutes and come up with "its the PCV valve" sure enough a part sent overnight from Christchurch and wahoo no more rough idle. I am thinking to my self "all these specialist people in this town and all the machines this car has been connected to and a 10 minute look from a guy with no training in BMW's finds the fault" Nothing like the help of a good mechanic. Just though I would mention this as all the places on the web I have been to and all the people I have talked to not one of them thought about the PCV valve. No disrespect for any of the guys here because you didn't see the car. Quote Share this post Link to post Share on other sites

elmarco 56 Report post Posted June 11, 2008 We normaly charge $40 for a scan + $75 an hour for diagnostic time. If its just a scan and report its $40 I think that rate is bloody reasonable. After all, if you had to pay for a professional in another field (insert pretty much what you like here - engineer, IT, psychologist, accountant) I would expect to pay over $100 per hour. And it isn't just the time spent hooking it up - there is the admin, invoicing, payment processing etc not to mention the cost of the tools to do the job. Glad the idle issues have been resolved - almost nothing worse than a gremlin in the engine! Quote Share this post Link to post Share on other sites
curryinahurry 39 Report post Posted June 11, 2008 hmm, someone mentioned squishy hoses... I've got a couple of those in my daily, what effect does it have? Quote Share this post Link to post Share on other sites
sp8s 1 Report post Posted June 11, 2008 Good stuff mate. Whats a PCV?PCV = positive crankcase ventilation, more info http://en.wikipedia.org/wiki/PCV_valveIn short the valve sucks all the gases out of the engine internals and burns through the induction system.squishy hoses = hoses that through contact with oil etc have lost their solid feel, sort of like a garden hose left in the sun. Cold its fairly solid but left in the sun it goes soft. Quote Share this post Link to post Share on other sites

No disrespect for any of the guys here because you didn't see the car. Great that it's fixed & proves you can't ignore the basic operating principals of an engine. These don't change. BUT, with modern cars there are any number of possibilities to cause some problems & with a modern cars diagnostic abilities it is much better to simply hook up a scanner first to identify a possible already diagnosed fault/s. As Glen said - with the skope - you can also monitor live time operation of the engine management system. If it confirms a problem - great! With nothing confirmed wrong in these fields - it then becomes a "back to basics" diagnosis to confirm the fault. Believe me - this procedure can prevent a lot of headaches when diagnosing problems. And yes - these scanners/skopes are expensive - ours was about 16k & now with updates costing around $500 - but boy they are a worthwhile piece of kit Quote Share this post Link to post Share on other sites
