  1. Tempted to say, the latter may cause the issue and the former may exacerbate it. Is the cooler a reputable brand? I've seen cheap copy part intercoolers arrive with holes in them due to really bad welds as well as not being able to flow anywhere near as well as a well regarded brand. The issue sounds like classic boost leak tbh. Have you pressure tested it the pipework?
  2. Yeah, blanking EGR will give you better performance for any given scenerio where the valve would be open. It might see you another 1-2mpg too. But given that Nox is a pretty nasty thing, i left it as is.
  3. I had mine remapped by e-maps.. Our main use of the vehicle then changed for a while (less motorway usage) and the DPF clogged. I had it removed and coded out. The coding out didn't affect the map. I kept the EGR, and cooler intact and later found the swirl flaps had already been removed - in theory you can introduce a dead spot low down in the rev range by removing the swirl flaps, but its better than the alternative of the engine being toasted.
  4. You're a mechanic? If so, easy stuff for you to do (if you haven't already)- -Check the car is reaching its target boost pressure (and reaching it at the target rpm, ie not full boost @ 4000rpm but under 2000rpm, maybe even 1500rpm). -Pressure test the pipework -Compression test the cylinders -Do an injector leak down test -Buy a scanner (C110, iirc?) - it'll read codes and I think it also does some of the tests, like injector smooth running test. At worst, you can use it on other cars you service/work on. Start basic, work methodically, and you will fix the issue:)
  5. haha.. I doubt anyone else has ever put their key in the lock manually! I also bet there is a large % of owners who don't realise the physical key slides out of the LCI fob!
  6. Anyone happen to know the steering rack ratio for the e60 model (not the variable rack). Not sure if its different for UK and other regions?
  7. As per my previous comment, you can check the link in my sig for more details on how I changed mine just so you have an idea. In fact, here you go - Its relatively easy, but if the pins that hold the connections together are corroded you will have a bit of fun getting them apart (same as I did). In my case it became a 2 man job at that point. You can always try up until that point, if you can't get the connections apart, put it back together and get someone else to do it.
  8. Maybe get someone to compression test it? If its getting enough air and fuel, I can only think its losing power via low compression.
  9. Someone else may be able to find the additional power, but the last thing you want is for someone to whack everything up to max without understanding the underlying issue. On a slightly separate note , is your engine quite mechanically noisy (not necessarily anything wrong) or quite quiet?
  10. Most likely a pin hole in the condenser (check my sig for replacement details). You can check to see if the clutch is engaging on the compressor with the engine running (it will spin periodically and then stop). If its constantly engaged it could be the compressor has failed (unlikely and expensive). If it doesn't engage at all, most likely the gas has leaked and the system is no longer engaging (due to low pressure).
  11. In fact, just having a look on the website and it lists front and rear diffs.. I remember my friend complaining about the cost, so maybe he did more than one! It is a bit odd on a 4wd, but I guess the added benefits are than it will prevent the wheel slip across the same axle (not just front and rear, where non-LSD'd 4wd comes into play), and reduces the final drive ratio to make the car feel quicker.
  12. I was wondering too, but just assumed the centre diff would sort out the difference in turning speeds. I'm also guessing the X5 isn't permenantly 4wd either? I thought it wasn't a bad price fitted tbh? Most retrofit torsen diffs seem to be in the region of around £1500-2000 fitted
  13. Friend of mine had one fitted to his X5. Said it really transformed the car. I think it also shorted the final ratio, so it felt quicker too. I'm surprised the 3.0 cars don't have an LSD as standard, but I guess its cost saving. Probably well worth it on a modified 535d / 545i upward.. but too costly for the other imo. To be honest, they don't seem to fit LSDs on many cars any more.. its an option on AMG mercs, non-existent on caymans, early XKRs etc..
  14. Thanks for the info guys Replacement looks like a headlight out jobby?
  15. One of my bulbs has gone pink.. so i guess its on the way out.. Am I right in thinking they are "D1S" fitment? There are some super cheap ones on ebay ranging from £12-30 for a pair.. compared to £60-90 for a single bulb from a decent brand/website... False economy or worth a punt?
