LDV G10 Gearbox & Transmission Problems

If the car drives forward then it’s possibly not the age-old problem of low or dirty transmission fluid that’s causing the problem. Even so, it may not be a catastrophic failure of the transmission and could, in fact, be as simple as a poorly adjusted gear selector cable or linkage. The sensors that operate the rear camera and reversing lights are not necessarily the same ones that actually select each gear, so the fact that they operate does not mean the transmission is physically selecting Reverse gear.

Have the vehicle looked at by a transmission specialist who will possibly have seen this very problem before. Don’t forget, either, that if the car has travelled less than 130,000km and has been serviced correctly, you may still be covered by LDV’s factory warranty which was for five years back when the vehicle was sold new. But get it looked at and the problem logged with LDV before that warranty runs out.

Your vehicle is interesting as it continues to use the old-tech hydraulic power steering, rather than the newer, more efficient electric power steering. This newer technology is simpler and potentially more reliable, but is used mainly because it saves a few drops of fuel.

In the case of your car, noise from a power-steering pump is often caused initially by low fluid. The power steering fluid doesn't just provide the hydraulic pressure to help you steer the car, it also lubricates the moving parts of the pump. If this fluid runs low, that lubrication doesn't happen, and the pump will wear quite quickly to the point where it seizes. It's a bit of a surprise that such a new vehicle would have this problem, but any sort of leak in the power steering system can lead to this low fluid level and the problems it causes. If you're lucky, the system might just need a top-up to make the noise go away. But if damage and wear has already started to occur, then the pump might be on the way out.

It's worth mentioning that your car is covered by a five-year/130,000km warranty. So, provided you haven't exceeded that mileage and the car has a documented service history, you may find that the problem is actually worthy of a warranty claim.

It’s a bit hard to imagine how removing and replacing a transmission could make an engine misfire or backfire. Unless, that is, you’ve managed to bump part of the engine’s electronic controllers, wiring, sensors or even something as simple as pinched or displaced a vacuum line somewhere in the engine bay. Incorrect ignition timing can make an engine do this, but, again, that’s nothing to do with the transmission.

It could even be a complete coincidence. But did the vehicle sit for any length of time while the transmission was being fixed? You might find the battery has discharged over time. Modern, electronically-controlled engines do not like low battery voltage and can run poorly as a result.

First things first; have the car electronically scanned to see what fault codes are thrown up. From there you can make a much more accurate diagnosis of the problem. Simply replacing random sensors and other parts on a hunch is a fast way to throw money away and still be stuck with a car that doesn’t run properly.

The de-carbonising process you mention is sometimes necessary in modern turbo-diesels which, for reasons of emissions control, consume a percentage of their own exhaust gasses as well as any gas build-up inside the actual engine. And since the exhaust gasses contain soot, and the crankcase gasses contain oil, those two compounds get mixed up into a black, gooey paste that clogs the engine’s intake system. At this point it usually needs to be pulled apart and manually cleaned. If this is the case with your car, it could well be the cause of the check-engine light and the poor running.
