Hi,

The two white wires are supposed to be connected to the terminal 1 (-) of the coil.
while the green-black should be connected to the terminal 15 (+)

There's no separate ignition module on t ...

Hi,

The "injection control unit" referred as S1(-S5) is used in the Jetronic system.
Are you sure that the drawing applies for the Motronic version?

Hi,

Until you have spark it is quite sure that the the signal from the flywheel sensor is reaches the ECU.

The injectors have ignition activated +12V supply on one terminal, the other terminal i ...

Hi Paul,

In case of Motronic the (thicker) white wire is driven by the ECU.
At the coil - terminal there's a branching towards the tachometer (thin white whire).
The unlike the Jetronic, the &quo ...

There is no electric fuel pressure sensor in the 33s. The priming is triggered by a simple timer within the ECU.
This timer responsible for the fuel cut-off when the flywheel stops turning over.
The ...

No short with ignition off. Just with key turned one click ie not engine running, but dash lit up.

Short symptoms disappeared with flywheel sensor disconnected.

Sorry, then I misunderstood some ...

Could a faulty crank sensor cause anything like this?

IMHO no. In case of flywheel sensor failure usually the engine not fires up.
Even if the sensor is faulty than cannot cause the phenomenons (i ...

Hi,

The white wires should be connected to the - terminal, marked with "1" on Bosch coils.

There's a two pole connector near the injector main and fuel pump relays.
Two wires were bel ...

I'm glad to hear that the starter was finally sorted.

For safety reasons the pump stops soon, when the ECU doesn't gets signal from the crankshaft sensor.
I've heard that some ML4.1 ECUs are not p ...

Hi,

It seems the #1 will be the winner.
The oil pressure warning light sender should have a white(ish) wire,
the engine overheating light sender has a thin brown wire.

Yes, the cranking attempts can be performed with the alternator
disconnected, it doesn't affect the operation of the starter.
But personally I'd not recommend to try with the alternator
disconnecte ...

Hi Paul,

If you don't hear a click when you turn the ignition key into start
position, then the starter solenoid is probably is not energized,
especially if the dash lights are not fading at all. ...

Hi,

The 8V hydraulic tappet heads are the same on the boxer engines
(including the 145/146 8V models).
The valve head diameters are 39.7 - 39.9 mm for the intake and
33.0 - 33.2 mm for the exhau ...

I've just realized that I already have a google+ account,
so here's the diagram with the arm length settings:

Hi,

you can have adjusters on the ends not depending
if you have or not power assisted rack

Fully agree with that, the difference is the length setting of the
steering arms. I don't know how t ...

Hi,

Poor running at low engine speeds could be caused by vacuum leak,
defective lambda sensor, or just the idle speed is set too low.

To test the basic ignition advance the hose must be disconn ...

Cheers LoneWolf, I've got one here for sale, but I've got a feeling postage to NZ these days would be pricey.
Thank you for the offer. Regarding the postage I agree, probably it would cost more than ...

Is there a trick to removing them?
Due surface corrosion of the upper section of distributor shaft, it's often hard remove the rotor arm.

You can try to lift off the dust cover as far as it go, ap ...

Do the IEs have same clusters as 16v cars, anyone ??

The speedo of the 16V models is scaled to 240km/h (instead of 220) and the
redline mark is higher on the rev counter, but from electronic and m ...

So its not un common for them to break then?
I was bench tested 4 or 5 instrument cluster from the post '90 serie,
not counting mine, and the rev counter was inaccurate in all of them.
(250 to 500 ...

There is a variable resistor inside the rev counter mounted on the PCB,
which is often fails, causing lower readings (usually after 6-10 years).
It's cheap to replace, but the rev counter needs to b ...

Hi,

I think the main reason of the power variation between the 1351cc engines is the fuel feeding.
Some models were supplied with single carb with double barrels, while other models were equipped ...
