Tech talk > 2019 911 Carrera GTS 4 convertible coolant leak from a plastic elbow at 18 000 kms . This is the " carnage " you need to do to replace a silly plastic elbow behind the water pump 😜. I'm not an engineer just a mechanic, my question is why would you put a plastic component on a ultra high performance twin turbo monster ?! The price of this vehicle was probably close to $ 350 000 or so ,carbon brakes for racetrack like performance, albeit the cooling system leaked just by standing, so I wonder what would it do on a racetrack 🤔? Ditto for the plastic oil pan !
The company is complaining they're loosing marketshare I wonder why? Any questions how may we help?

Tech talk > 2015 X3 xdrive Diesel charging issue at hand . Owner tried to fix the problem but after the second alternator replacement and numerous batteries he give up . Initial testing revealed a massive 2V difference between the alternator and the battery. Voltage drop test revealed a major resistance along the length from rear to the front . The culprit found to be the distribution box at front where the JBE and the forward wiring harness is split . Appears to be someone accidentally left the junction partially loose which melted the junction/fuse box aft of the windshield. Naturally all is back to normal after junction box replacement. The 911 was in for a new battery and maintenance. Any questions how may we help? bmwspecialist bmw

Tech talk Mercedes-Benz GLC 300 2016 and CLA 250 2018 camshaft and crankshaft correlation faults . Unfortunately both engines the M274 GLC and the M270 CLA has identical manufacturing faults, the camshafts are off from their desired position due to the hubs moving over time . This camshafts are hollow and the lobes and hubs are fitted and secured via friction lock only in a jig . Unfortunately they tend to move off slightly from their desired position over time and will set a camshaft crankshaft correlation faults. The manufacturers says to replace the camshaft with a new revised version to correct this problem. Any questions how may we help?

Tech talk > 2018 BMW 540 Diesel transfer case service made easier via Techmax Auto by making a small threaded drain hole to ease servicing. Unfortunately BMW has this daft idea not to provide a drain hole > they call it a lifetime fluid ,non sense! We have a plethora of all BMW's with transfer case chattering and jerking due to transfer case lack of maintenance. The other picture of spark plugs replacement in a Bentley Continental GT W12 ,which is two VR6 engine fused together. The green Porsche Taycan 4S was in for no A/C complaint. Unfortunately the DC/DC converter is defective which needs to be rectified first before proceeding any further. Any questions how may we help?

Tech talk > two completely different era of BMW finest . Pristine M5/// with seized front brake caliper at the right front . Since the part is NLA we fixed both front calipers with new seals and dust shields ,it's a no biggie. I love to fix things instead of toss them , a little bit of finesse goes a long way . Pistons and bores were cleaned and polished, reassembled with the outmost care and she works like nothing ever happened. The other one is the carbon fiber bodied IX50 which is a sort of a successor to the i3 . Was in for a genuine BMW specific ( solar/ accoustic/ HUD ) windshield replacement and ADAS calibration. Interesting to note the washer fluid filler door is the hood emblem, cool . Any questions how may we help? bmw windshield
