Well, it is you asked, but it very much looks like one of the rear springs is giving up.

Re: Yet more engine issues

You found the culprit, I suppose. Start by replacing the filter, no harm done anyway. If still no return the pump should be checked.

Re: Yet more engine issues

Perform a reset on the roboumod and check if the problem is right there from the beginning. Both ECUs may be in some loop as a result of turbo spikes or some ignition anomaly. Also check the vacuum in the air pipe to the ECU. This is no cure but it may give a direction of where to find a solution.

Re: Blinky 51/480

In some cases circuits in which the DRL's are included in the defect check are affected: The warning light stays on. Just do away with the bulb failure detector in the relais box. The rear bulbs check will remain. The resistor idea is nonsense. They are in parallel with the bulbs so always cause a c...

Re: Extreme Speedo Rescue

When shielding is used for equalizing potential it is not shielding anymore. Shielding should be connected only at the input ground preferably.

Re: Erm, engine won't start, seems to be flooded with fuel

When you tapped the accelerator you made the throttle valve go into it's closed position. The cable gets stuck somewhere. It has nothing to do with the idle valve. Oil and/or loosen the cable a bit and check if the accelerator comes up all the way. If at starting the throttle valve was not at it's i...

Re: Rough running - B18FT

All symptoms, except the long time to start, sound like being caused by the MAF. Check first if you replaced it by the correct type, number ending by 007 or 021. Then clean the connector and if no success move the wiring to and fro. You may reconnect a broken wire in doing so. When idling is normal ...

Re: Engine Electrics

@yorkievolvo: Not any coil, I stated coil meant for transitorized ignition, today's cheap standard. And after Alan 480's post I may add a coil meant to be used with a balast resistor but then used without the resistor. "Any" coil would include the coils meant for use with breaker points which could ...

Re: Engine Electrics

Some odd misinformation here. The turbo has just a cheap standard coil for transistorized ignition. The coil connects to 12V at ignition on. A small module, holding two transistors, is connected to the other spade on the coil and connects/disconnects to ground. The latter action causes a spark. This...

Re: YANIC problem!

When you take the infocenter fully apart you'll notice the elecrical connections to the glass substrate are made by a strip in which there are conductive parts. Both ends may have a failing contact. Clean the surfaces with whatever you find appropriate and may be you find a way to put more pressure ...

Don't cheer too early, it's inside the ECU EZ210K. Next questions: Location? Under the upholstry at your left leg. How's that? Sitting in the drivers seat.

Re: Running On

Very intriguing! The "dieseling" needs fuel. Injection being multi point or "semi" multi point shouldn't matter, it is activated in some way. Now when the ignition is switched off it is only effective as far as the spark is concerned, because the ignition coil is effectively powered off. But the ECU...

Re: Coil pack question... car doesn't start

I would say for a starts study some diagrams and get power to the coil, the fuel pump etcetera. It is difficult to advice given the circumstances you describe. Think of a logical scheme and take care of one problem at a time.

Re: Coil pack question... car doesn't start

No power on the ignition coil has for the time being nothing to do with the coil nor the electronic pack. The coil is powered after ignition on and the pack switches the other connection to ground and releases when a spark is due.

Re: URGENT: need throttle brass screw

If this #3 is indeed the screw you're worried about, just use anything to plug the hole. There's no use for it. Let alone for adjusting idle.

Re: Battery Charging

The gauge is all but an exact indicator. Check the voltage which a multimeter over the battery, lights, fans and AC off. If it is well over 14 Volts exchange the regulator in the alternator.

Re: Didn’t pass MOT/TÜV…Spanish ITV

@balto8 The resistance between pins 2 and 6 on the MAF from where to begin adjusting is ±320Ω. If a mod is involved I advise ±520Ω. Remember the set value, during a MOT it may be necessary to change it. Removing the MAF connector will have strange effects. Revving up quickly will cause a well-adjust...
