http://item.mobileweb.ebay.co.uk/viewitem?itemId=290783858395 I have been thinking about uprating the springs on my 400h for the same reason. Has anyone on here fitted the eibachs?
Where did you buy it from and what is your opinion of it, sound/performance etc? It looks really good and so does the exhaust but will need to part with nearly £1500 for the pair...
Camshaft bank 2 sensor is pretty easy to change and is on the front cylinder head on the right hand side as you look under the bonnet and is fixed in by a 10mm bolt and a multiplug. These are quite common faults.
Mine was under warranty at the time so was free. If you buy the latest hdd update which includes 2013-14 version 2 maps and gracenotes you will also get the software update included. This costs about £140 plus vat.
