What to watch out for

Steering too light and feel-free at speed. Gearchange of Z4M a bit clunky. Difficult to drive Z4M smoothly.

When Runflats fitted, TPMS valves prone to failure due to corrosion battery effect between metal valve caps and the valve stems. This is easily prevented by fitting plastic instead of metal valve caps.

If the car has Bluetooth and the owner has their Mobile phone synched to the car then if the car is not locked / all electrics shut down the car will keep trying to search for the phone and drain the battery.

31-5-2015: 86k mile 2007 BMW Z4 coupe (3.0 litre N52 engine) developed low power and pinking last year. Local dealer diagnosed faulty Vanos solenoids and Valvetronic motor and replaced them. For a while, the car ran beautifully again but the same problem has now returned. The dealer says BMW diagnostics are not showing any codes and so, supposedly, there is no fault with the vehicle. The car has a full BMW history and is under extended warranty. Injector cleaner through the engine had no effect.

Recalls

15-4-2014: Worldwide recall of 489,000 BMW cars with six-cylinder N52 3.0 litre petrol engines of which less than 3,000 are in the UK. The screws for the housing of the adjustment unit of the variable camshaft timing (Vanos) for the intake and exhaust camshafts could potentially become loose or break. An engine warning lamp ‘should ’ appear in such circumstances, but if drivers experience any loss of power they should contact their BMW dealer immediately.

28-7-2014: R/2014/068 BMW 1, 3, 4, 5, 6, X1, X3, X5, Z4 Build Dates 1-9-2009 to 30-11-2011: Concern : ENGINE EMERGENCY MODE MAY BE ACTIVATED DURING DRIVING Description : The screws retaining the variable camshaft timing (VANOS) housing may loosen and under certain circumstances the heads may break off. This can lead to the VANOS leaking oil internally and adversely affect the valve timing adjustment. If found to deviating from targeted data the engine emergency mode will be activated. This will be indicated by a distinct change in engine running. The orange engine management warning lamp and a check message; On vehicles with N51/N52 engines this will appear at ignition recycle, on N55 engine it will display immediately. Remedial Action : Replace bolted connection of the VANOS adjustment unit.

10-4-2017: R/2017/114: BMW 1-Series; 3-Series; Z4 and X1. PLUG-IN CONTACT CABLE MAY MALFUNCTION. It is possible that the connection between the B+ cable and the Power Distribution Box can become damaged by wear and heat, which is caused by high current flow and high contact resistance. Normally, this will result in a non-start situation after parking the vehicle. However, it is possible that this could, in extreme cases, occur whilst the vehicle is in motion. The driver should be made aware of the issue by flickering of the instrument cluster (dash) or an engine mis-fire; but if the driver does not, then the engine could cut-out without warning. Fix: Recall all affected vehicles with petrol engines and replace the cable/connection with a more robust item. Build dates 1-12-2009 to 13-10-2011.

9-5-2018: Recall because wiring configuration means that vehicle vibrations could potentially cause frictional corrosion on the plug of the power distributor causing the car's engine to cut out.
