As some of you who've been reading stuff on ClubVR4 (and some NZ members) will know, one of the most common problems with the AYC system in VR4's is the pressure switch. This problem is exacerbated by the AYC hydraulic pump losing pressure as it ages, causing the pressure switch to trip less and less frequently due to the high pressure required for the stock switch, which is further compounded in hot weather (such as we get all the time) as the fluids heat up and become more viscious. In the UK, Malc supplies a replacement switch set to 9 bar (130psi) which relieves these problems (unless your pump is screwed completely), and he even did some legwork for us by finding a company in Australia who make a similar product here. I've just been in contact with ANZ Controls and obtained pricing on these for those who are interested. The unit you want is as follows: Pre-Facelift - Model 0167 Part Number 670 812 003 normally closed pressure switch set to 9 bar (130psi). Facelift - Model 0167 Part Number 670 712 003 normally open pressure switch set to 9 bar (130psi). **Please note: Early facelifts actually use the normally closed switch, as per Malc's post below. Only vehicles manufactured from 2001 on used the normally open switch. If you're unsure, take a look at the switch on your AYC pump - if it has a black top its normally closed, green top is normally open. MAKE SURE YOU USE THE CORRECT SWITCH!!** These are AUD$93.50 each. You can also get the pressure set by them for $8.80 per unit. Shipping is via courier at $22 to all states and is usually next day delivery. The optional rubber cap with dual cable duct (Part Number 662 100 003) is an extra $10.45.
