It is supplied as an original equipment part and comes as one each, which is important when matching a replacement to the vehicle’s electrical and mounting requirements.\u003c\/p\u003e\n\u003cp\u003eThe unit has 3 mounting bores and is identified as a starter motor in the rotating electrical group. Those details matter when comparing the replacement to the original unit, particularly where the starter housing, bolt pattern, and pinion tooth count need to line up exactly for correct installation.\u003c\/p\u003e\n\u003cp\u003eFitment references supplied for this part include Audi Q7, Porsche Cayenne, Porsche Panamera, and Volkswagen Touareg applications. Those vehicle names can help narrow the search, but the safest way to confirm suitability is still to match the part number, voltage, rotation, tooth count, and mounting details before ordering.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eOriginal equipment part\u003c\/li\u003e\n\u003cli\u003e12V starter motor\u003c\/li\u003e\n\u003cli\u003eClockwise rotation\u003c\/li\u003e\n\u003cli\u003e9 tooth pinion\u003c\/li\u003e\n\u003cli\u003e3 mounting bores\u003c\/li\u003e\n\u003cli\u003eSupplied each\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePart No.: 1986S00978\u003c\/li\u003e\n\u003cli\u003eBrand: Bosch\u003c\/li\u003e\n\u003cli\u003eProduct type: Starter motor\u003c\/li\u003e\n\u003cli\u003eVoltage: 12V\u003c\/li\u003e\n\u003cli\u003eRotation: CW\u003c\/li\u003e\n\u003cli\u003eNumber of teeth: 9\u003c\/li\u003e\n\u003cli\u003eNumber of mounting bores: 3\u003c\/li\u003e\n\u003cli\u003eUnit of measure: Each\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eKnown fitment references\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAudi Q7\u003c\/li\u003e\n\u003cli\u003ePorsche Cayenne\u003c\/li\u003e\n\u003cli\u003ePorsche Panamera\u003c\/li\u003e\n\u003cli\u003eVolkswagen Touareg\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplication and Buying Notes\u003c\/h3\u003e\n\u003cp\u003eBefore ordering, compare the existing starter against this Bosch unit using the key identifiers: 12V voltage, clockwise rotation, 9 tooth pinion, and 3 mounting bores. These are the practical checks that help confirm the replacement matches the vehicle’s original starter layout and engagement setup.\u003c\/p\u003e\n\u003cp\u003ePart number matching is the strongest verification point here. If the removed starter or the vehicle catalogue cross-reference shows 1986S00978, that is the clearest indication you are looking at the correct unit. If the part number differs, do not rely on appearance alone, as starter motors can look similar while differing in rotation, tooth count, or mounting arrangement.\u003c\/p\u003e\n\u003cp\u003eThe listed fitment references cover Audi Q7, Porsche Cayenne, Porsche Panamera, and Volkswagen Touareg applications, but model naming alone is not enough to guarantee compatibility. Engine variants, production years, and factory changes can affect starter selection, so it is worth checking the original starter, the vehicle details, and any catalogue notes before purchase.\u003c\/p\u003e\n\u003cp\u003eBecause this is an electrical rotating assembly, careful comparison before fitting is important. Confirm the unit is intended for 12V systems, that the mounting bores align with the existing installation points, and that the clockwise rotation matches the original starter’s direction. A correct match reduces the chance of installation issues and avoids unnecessary removal work.\u003c\/p\u003e\n\u003cp\u003eBefore supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.\u003c\/p\u003e\n\u003cp\u003eFor workshop, fleet, and equipment applications, accurate identification of part number 1986S00978 helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.\u003c\/p\u003e\n\u003cp\u003eRelevant published details for this unit include Type STARTER MOTOR, Unit of Measure EACH, Warranty 24 Months, Rotation CW, Number of mounting bores 3, Packaging width 18, Manufactured in China, Product Group 1 ROTATING ELECTRICAL, Part No. 1986S00978, Brand BOSCH.\u003c\/p\u003e\n\u003cp\u003eAdditional published details for cross-checking include Description Bosch Starter Motor 12V 9Th CW, Number of Teeth 9, Voltage 12, Packaging length 32.5, Packaging height 13.9, Product Group 2 STARTER MOTORS.\u003c\/p\u003e\n\u003cp\u003eBosch Starter Motor 12V 9Th CW. Part number 1986S00978 should be checked first. Listed voltage is 12. These details form the core reference points used by parts interpreters when confirming the correct replacement.\u003c\/p\u003e\n\u003cp\u003eFor part number 1986S00978, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details. Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.\u003c\/p\u003e\n\u003cp\u003eFor a starter motor in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 should be checked carefully.
