You need to clean the throttle and perform an idle relearn. Unfortunately there isn’t a reset function in Techstream or other software, you can only do it manually. This is the way I do it, some people say to hold the throttle plate closed on the first key on. I find it to be unnecessary and tends to lead to having to do the procedure multiple times. First ...

This isn't coolant, because it wouldn't rust if it was (coolant has rust inhibitors) - so I'm not going to declare a head-gasket failure (although a sniff test at the garage might indicate something). Check the spark plug cover to see if it's loose - a quick research showed that that can sometimes be the issue, catching incoming rain and directing it down ...

It is struggling in the thinner atmosphere as your height increases. You need to increase the amount of air going into the engine to have any chance or get a larger bike with more low end torque that won't notice the losses so much. Edit to reply to comment about changing rear sprocket for a larger one. Yes, you can do this, but you limit the top end speed ...

I know that these cars have issues with the timing chain tensioner and in some countries there was a BMW recall on the N47 engines specifically for this. A recall is where a manufacturer admits there was a problem and rectifies it free of charge. The very first thing I'd do is establish if the cam timing is still in sync with the bottom end. There are a ...

The culprit was a seized EGR valve. I was under the impression that emission related issues would always throw a CEL. Turns out that I was wrong. The code reader revealed a P409 without CEL, later steps were easy. I removed the EGR valve, found it stuck, cleaned and reinstalled it.

Here's the breakdown of the power distribution from Fuse #6. You have a roof console unit, keyless receiver unit (George may be on to something), handsfree control unit, and some other gizmos which might be "smart" and cause the kind of pulsating timed loads you describe. An active key in the vicinity might cause such a thing. The key is "waking up" the ...

I'd check that your lift pump / swirl pot is working. The way the GTI and VR6 fuel system works is that there is a relatively low pressure fuel pump that pulls fuel from the tank into a "swirl pot" and it's from this pot that the high pressure fuel pump draws fuel. If this pump isn't working, you won't have anything constantly refilling the swirl pot so in ...

Bent valves mean that the pistons hit them (timing) or the valves didnt retract (valve float). The hydraulic lifters are excellent at low and mid-RPM but can cause valve float at high RPM as the mechanism that allows zero-lash at low RPM works against the valve at high-RPM. As engine rpm increases, the bleed down rate inside the lifters may be too ...

I would replace the sparkplug cable - age makes them susceptible to moisture ingress causing loss of spark. You may see stray sparks when it is dark...

Catalytic converters can go bad pretty quickly when engines are out of tune. p0420 is possibly that. The definitive test is a pressure gauge where the O2 sensor is. If the compression on the motor is good (compression test) you need to look elsewhere. If compression is low on all cylinders - timing belt jumped a tooth. Vacuum gauge will also give you an ...

To me the P0328 makes a ton of sense. This web page states a P0328 code can be caused by: Faulty knock sensor 1, bank 1 Open or short in knock sensor circuit wiring Failed ECU Wrong octane fuel or lean air fuel ration Engine is overheating Low fuel pressure One of the major symptoms of this (other than the CEL) is a loss of power. If the knock sensor is ...

It's hard to say, as there isn't much info to go on. A few things to check: 1) Check the spark plugs to ensure you're getting a good spark. Replacing them could help. 2) Make sure you're using fresh fuel. If you have a fuel filter, try replacing it with a new one. Has the bike been sitting unused for any length of time? Bad fuel or fuel that has been ...

If your vehicle has a manual trasmission, its possible that your clutch is going out. If the revs are going up when you hit the gas but you don't feel the power getting to the tires, then its probably the clutch. Here is a video that shows you a few tricks on how to diagnose a bad clutch https://www.youtube.com/watch?v=h7JJ_g2UuBI Another trick not ...

This is called "bogging", so you can know what to google. It feels like fuel delivery but can be electrical. Check your spark plugs to see if they (it) are (is) fouled. Replace it. Then drain all your gas and replace it. Water in the gas can cause this as well. If you have begun to store it outside, you may want to move it inside. Also, timing could be a ...

If you overfilled the oil - then the excess can be forced into the induction system and, as it is diesel, this provides extra "fuel" for the engine causing it to over-rev. You need to read the codes and you may have a chance of sorting it. There are videos of this happening to diesel engines on **otube, and it can be terminal ie the engine damages itself - ...

Turned out to be the fuel pump. It's getting replaced on warranty :D

Regarding the issues when the engine is warm: Check your coolant temperature sensor and its wiring. If the engine control module (ECM) does not get a correct reading from the coolant temperature sensor, it assumes the engine is cold. On a cold engine the ECM changes the fuel mix to be more rich as this is required in cold conditions to properly start and ...

Edit: I didn't look at the OP date before replying, just saw this in recent activity. Leaving my answer to help in the future, anyway. Is this car an automatic transmission? And if so, does it feel like a manual car with a dragging clutch? Can the engine rev in neutral when in this condition? If so, the torque converter might be somewhere to look. ...

Check that the two earth straps are in place; there's one on each side of the engine, attached between the engine and the body. You're looking for two braided cables, about six inches long each. It's easy to forget that their there (I've ripped out several when removing Subaru engines)

If you have the Duratorq engine, which is also used in the Jaguar, then the location of that sensor is in the pipe on the lhs front of the engine coming up from underneath and connecting to the EGR valve which is top left hand front corner of the engine. The left hand side is standing at the front of the car looking at the engine - the right hand side has ...

The 2.2L L61 engine doesn't use a traditional camshaft position sensor. The ignition control module senses firing events. Then generates a CMP signal to send to the PCM. This could be a wiring issue, a failure in the ICM or a secondary ignition problem (e.g. spark plugs/coil pack). A clean CMP signal needs to be confirmed at the PCM and make sure that the ...

Though you have a small engine, and the difference will be minimal, but increasing intake manifold runner length will move torque curve lower in the RPM range. But this will affect peak torque figures, as well as engine revving character - it will not be as rev-happy.
